Thought for a second
Based on real, available security‐and‐anti‐theft solutions, one promising 
approach is to combine two types of products into a system that meets your 
requirements:

A Locking, Tamper-Resistant Universal Phone Case:
Look for a case that “locks” onto your phone—one designed for retail demo units 
that secure internal compartments. For example, some security solutions for 
store display phones use a heavy-duty, metal‑reinforced case with a keyed 
locking mechanism. (Products from security brands like InVue or secure display 
solutions for kiosks sometimes offer “locking” enclosures that require a 
physical key (or a cutting tool) to remove the phone.) These cases typically 
enclose the phone fully so that battery or SIM access panels are not accessible 
without unlocking the case.

A Universal Anti-Theft Tether/Anchor:
In combination with the locking case, you can attach a heavy-duty tether (such 
as the ClutchLoop Universal Anti-Theft Phone Tether or similar real security 
tethers available commercially) that secures the phone to a fixed object (or 
your body, in a discreet way) during daily use. This means that even if someone 
tries to pry the case open or remove the phone, they’ll have to contend with 
both the physical locking mechanism and a tether that resists quick 
snatch-and-run theft.

Real-World Options:

InVue Secure Display Solutions: Although originally designed for retail display 
devices, several models are built to be “tamper-proof” (locking enclosures that 
prevent access to internal controls). Some vendors offer “portable security 
cases” that can be adapted for daily use; they’re usually made of hardened 
metal or reinforced polymer and require a key for removal. Ask a local security 
supplier or search for “InVue locking smartphone case” or “secure retail demo 
phone enclosure” to find a model that fits your phone’s dimensions.
Kensington Secure Smartphone Lock: Kensington is a well-known name in security 
hardware. Their security cables and locks (often used for laptops and 
smartphones in public spaces) sometimes come with locking phone cases or 
attachments that can be integrated into a custom solution.
Custom-Built Solutions: Some security suppliers offer modular anti-tamper 
enclosures designed for mobile devices. For example, you might use a standard 
heavy-duty smartphone case (from a manufacturer of rugged cases) that is 
modified with an external locking mechanism (or paired with a security kit) 
that seals off battery/ SIM compartments. Look for “tamper-resistant smartphone 
security kits” from vendors specializing in anti-theft hardware.
How This Addresses Your Needs:

During Use Protection: Unlike cases that are designed only for storage, these 
locking cases are built so that the phone’s screen, controls, and speakers 
remain fully usable while the case stays locked (you simply unlock only when 
you want to remove or access the internals).
Universal Fit: Many of these solutions are designed with adjustable or 
“universal” enclosures to work with a wide range of phone sizes and shapes. 
Some products let you attach a universal adhesive plate to your phone so the 
locking case fits securely even if your phone’s shape isn’t standard.
Composed of Real Products: Kensington and InVue are established brands, and 
many security suppliers provide retail-grade locking enclosures for public-use 
devices.
If you’re interested, I can help narrow down a specific model or combination 
that suits your exact device size and daily usage scenario (running, listening 
to music, offline maps). Would you like further recommendations or details on 
how to assemble such a system?

Below are a few real, high‐quality products and components that security 
professionals use to “lock down” a phone for daily use while still allowing 
full functionality:

ClutchLoop Universal Anti‐Theft Phone Tether
– A rugged tether system made with a woven, cut‐resistant steel cable and a 3M 
adhesive plate that sticks to virtually any phone. It comes with a locking 
carabiner so that the phone remains secured during use.

Kensington Mobile Device Security Solutions
– Kensington offers a range of anti‐theft locks for mobile devices. Their 
mobile device locks (often used in public spaces) incorporate keyed locking 
mechanisms and steel cables that can be paired with a robust phone case.
Explore Kensington Mobile Device Security

InVue Secure Display Enclosures
– Originally designed for retail demo devices, InVue’s locking enclosures are 
engineered to prevent tampering and unauthorized access. Many of these 
solutions are “universal” in design and can be adapted for personal use where 
internal access (battery/SIM) must be blocked without sacrificing daily 
usability.
See InVue Security Solutions

In many cases, these solutions are used in combination—for example, mounting a 
ClutchLoop tether to a rugged locking case (or using an adapted InVue 
enclosure) ensures that the phone is fully usable (for music, maps, etc.) while 
its internal compartments remain inaccessible without the proper key or tool. 
If none of these off-the-shelf solutions perfectly fits your device, many 
security suppliers also offer custom or modular anti-theft kits designed for 
“demo” phones that you can adapt to your specific model.

Based on what you’re looking for—a daily-use, tamper‐resistant setup that pairs 
with the ClutchLoop tether—we haven’t found an integrated “lockable” case 
marketed specifically for mobile use. Instead, many users combine a proven 
anti‐theft tether (like ClutchLoop) with a rugged, tamper‐resistant case that’s 
designed to withstand heavy use and deter casual tampering.

Here are some real-world options to consider:

ClutchLoop Universal Anti‐Theft Phone Tether
(This is the tether you already looked at.)

Rugged, Heavy‑Duty Phone Cases:
– OtterBox Defender Series:
Known for its multi-layer protection (including a solid outer shell and inner 
shock absorbers), the Defender Series is popular for those needing extra 
security. Although it isn’t “lockable” in the sense of preventing SIM or 
battery access, its robust build makes it much harder to force open without 
proper tools.

– RhinoShield SolidSuit (or similar RhinoShield products):
RhinoShield offers extremely durable cases that are designed to absorb shock 
and resist tampering. Their modular design makes them adaptable to various 
attachments, meaning you can secure the case (and thus your phone) with your 
ClutchLoop tether.
Full URL:

Why Not InVue or Kensington for On-the-Go?
– InVue’s secure enclosures and Kensington’s solutions are typically designed 
for retail display or stationary installations. They often require a fixed 
anchor (like a desk or kiosk) and a key-based lock that isn’t practical for a 
phone you plan to use while running, commuting, or sleeping.

For your needs, the best approach appears to be pairing the ClutchLoop tether 
with a rugged case—like one from OtterBox or RhinoShield—to create a two-layer 
security system. The tether will force a thief to deal with a strong, 
cut-resistant cable (and its locking mechanism, if available), while the 
heavy-duty case adds extra physical protection that makes accessing the battery 
or SIM difficult without the key or proper tools.

Would you like additional help with finding the exact model that fits your 
phone’s dimensions or further advice on mounting these together for daily use?

Can you review case options for tamperproofness? I don't immediately see 
rhinoshield offer lockability
Reasoned for 23 seconds
While truly “tamper‑proof” phone cases that physically lock out access to 
internal components (battery, SIM tray, etc.) do exist, most of these are 
designed for retail demo units or stationary kiosks—not for on‑the‑go daily 
use. Here’s a review of your options:

Locking Enclosure Cases (Retail/Demo-Style):
Products from companies like InVue or Kensington are built to secure phones in 
public displays. They often use a metal enclosure with a keyed or combination 
lock. In practice, these are bulky and require a fixed anchor (like a desk or 
kiosk), making them impractical for portable daily use such as while running or 
sleeping.

Rugged, Heavy‑Duty Cases:
Cases from brands such as the OtterBox Defender Series or similar rugged 
options are designed to protect against drops, impacts, and even forced 
opening. Although they don’t “lock” access to the SIM or battery compartments 
via a mechanical key, their robust construction means that prying them open 
requires specialized tools and significant force.

https://www.otterbox.com/en-us/defender-series
• RhinoShield (while not offering an integrated lock, their modular designs are 
extremely durable):
https://rhinoshield.io

Combination Solutions:
For portable daily use, many users combine a high‑quality anti‑theft tether 
(such as the ClutchLoop Universal Anti‑Theft Phone Tether, which attaches via a 
strong adhesive plate and features a cut‑resistant steel cable) with a rugged 
case. This two‑part approach doesn’t “lock” the phone internally, but it does 
significantly increase the physical barrier to theft.
• ClutchLoop URL:
https://clutchloop.com

Summary:
Mainstream tamper‑proof cases with a built‑in locking mechanism (similar to 
those used for retail demos) aren’t widely available for everyday portable use. 
Instead, the best practical solution is to use a rugged case (like OtterBox) 
that resists forced entry and pair it with an anti‑theft tether (like 
ClutchLoop). This combination makes it extremely difficult for a thief to both 
remove the phone and access its internals without specialized tools or keys.

What do professionals for whom the contents of their phone are a serious 
security risk use? Like what would somebody take into an environment where they 
wouldn't want their phone captured by an adversary?
Reasoned for 24 seconds
For professionals who face real risks of adversaries capturing or tampering 
with their devices, there are a few approaches and products that are commonly 
used:

Hardened Smartphones with Custom Security Operating Systems:
Many security experts and journalists use a Google Pixel device running a 
hardened, open‑source OS like GrapheneOS. This operating system removes many of 
the tracking and vulnerability vectors found in stock Android, providing 
enhanced protection against remote exploits.
– GrapheneOS website (full URL):
https://grapheneos.org
– Recommended devices are often the Pixel 7 or Pixel 8 series, which are 
officially supported by GrapheneOS.

Purpose‑Built Secure Devices:
Some organizations and high‑risk professionals opt for devices built from the 
ground up with security in mind. For example:
– Bittium Tough Mobile: This rugged smartphone is designed for government and 
military applications and incorporates multiple layers of hardware and software 
security.
Full URL:
https://www.bittium.com/products/tough-mobile/
– Purism Librem 5: An open‑source smartphone with hardware kill switches (for 
camera, microphone, and connectivity) designed for privacy and security.
Full URL:
https://puri.sm/products/librem-5/

Physical Security Measures:
In high‑risk scenarios, even a hardened smartphone might be at risk if 
captured. Many professionals also use additional physical measures such as:
– Keeping the device in a Faraday bag or lockable, tamper‑evident case when not 
actively in use.
– Using an anti‑theft tether like the ClutchLoop Universal Anti‑Theft Phone 
Tether (full URL: https://clutchloop.com) to secure the device to a fixed 
object or to your person.
– Using a “burner” phone that is dedicated solely for sensitive communications.

In practice, many high‑security users combine these approaches. For example, 
they might use a Pixel running GrapheneOS for day‑to‑day secure communications 
but keep it physically secured (e.g., stored in a Faraday bag or attached to a 
tether) when entering environments where the phone could be physically seized. 
This two‑layer strategy—software hardening plus physical security—helps 
mitigate both remote and physical capture risks.

Would you like more detailed comparisons of these devices or advice on how to 
integrate physical security measures with your chosen phone?







You said:
I'm concerned that a technically advanced pickpocket or criminal misusing drugs 
could hack a phone with physical access while it is still tethered, even if it 
is faraday shielded. I'm concerned that this possibility isn't addressed in 
your reply.
Reasoned for 13 seconds
Even with robust measures like a tether and Faraday shielding, a determined, 
technically advanced attacker with physical access might still attempt to 
compromise a device. Here’s a more detailed look at what professionals do to 
mitigate that risk:

Hardened Device & OS:
Many high-risk professionals opt for devices running hardened operating systems 
(e.g., a Google Pixel running GrapheneOS or a purpose‑built secure phone such 
as the Purism Librem 5). These devices often include hardware kill switches for 
wireless radios, cameras, and microphones that let you physically disable 
potential attack vectors even if someone gains brief access.
• GrapheneOS: https://grapheneos.org
• Purism Librem 5: https://puri.sm/products/librem-5/

Tamper‑Resistant Enclosures:
For scenarios where physical capture is a risk, some users employ 
tamper‑evident, lockable cases. While these types of cases are common in retail 
demo environments (e.g., InVue or Kensington solutions), they are usually too 
bulky for everyday use. Instead, professionals might use rugged cases (like the 
OtterBox Defender Series) that—although not “locked” per se—are extremely 
difficult to pry open without specialized tools.
• OtterBox Defender Series: https://www.otterbox.com/en-us/defender-series

Physical Isolation & Operational Security:
Even the best software and hardware measures have limits when an adversary 
gains physical access. To address this:

Faraday Bags/Enclosures: When not in use, a high-risk professional might store 
their secure device in a Faraday bag or a similar tamper‑evident enclosure, 
ensuring it remains offline and inaccessible.
Limited Exposure: Use a “burner” or secondary phone for non‑critical 
activities. The secure device is then reserved strictly for sensitive 
communications and is never left unattended.
Tamper-Evident Seals: Some security solutions include seals or sensors that log 
or alert you to any physical tampering attempts.
Layered Security Approach:
No single measure is foolproof. High-security users rely on a combination of 
hardened hardware, secure operating systems, robust physical protection 
(tethers plus rugged cases), and strict operational practices (never leaving 
the phone unattended, using kill switches, etc.). This layered approach 
increases the complexity and cost for an adversary trying to compromise the 
device.

In summary, while a tethered, Faraday-shielded phone significantly raises the 
barrier for an attacker, professionals at very high risk also use hardened 
devices with hardware kill switches, store them in tamper‑evident enclosures 
when not in active use, and follow strict operational security protocols. 
Ultimately, if an attacker does gain physical access, the goal is to ensure 
that any compromise would be extremely costly and time-consuming—ideally 
deterring even a sophisticated pickpocket or criminal.

Would you like more detailed guidance on configuring any of these measures 
together for your specific environment?







You said:
what about a general-purpose box with a locking ring?
Reasoned for 30 seconds
There isn’t a widely adopted, off‑the‑shelf “general‑purpose box with a locking 
ring” specifically designed for a phone that still allows everyday use (like 
using apps, maps, or music) while protecting its internals. In many high‑risk 
or high‑security environments, professionals have taken one of two approaches:

Stationary or Kiosk‑Style Enclosures:
– These are designed for public displays or demo devices rather than for use on 
the move. For example, solutions from InVue or Kensington provide secure 
enclosures that physically “lock” the phone inside a box with a locking ring or 
keyed mechanism. However, they’re bulky and require a fixed anchor (such as a 
desk or kiosk) so they don’t allow the phone to be used normally while you’re 
moving around.
(For instance, InVue’s secure display stands can be seen here:
Full URL: https://www.invue.com/solutions/secure-display-enclosures/
Note: These are typically for stationary retail setups.)

Portable Combinations:
– For on‑the‑go protection, many professionals use a layered approach:
• A rugged, tamper‑resistant phone case (like those in the OtterBox Defender 
Series, which is very hard to force open without specialized tools)
Full URL: https://www.otterbox.com/en-us/defender-series
• An anti‑theft tether system such as the ClutchLoop Universal Anti‑Theft Phone 
Tether
Full URL: https://clutchloop.com

While neither component alone “locks” access to the internals, together they 
significantly raise the barrier to unauthorized removal. The rugged case makes 
it very difficult for someone to pry open the phone to access the battery or 
SIM, and the tether forces a thief to contend with a strong, cut‑resistant 
cable (often featuring a locking mechanism on its anchor).

Why a General‑Purpose Lock Box Isn’t Common for Mobile Use:
A true lock box that fully encloses a smartphone—while preventing any 
tampering—would naturally block your ability to interact with the device. In 
high‑risk situations where physical capture is a concern, some professionals 
simply avoid leaving their device unattended at all. They might switch to a 
“burner” phone for non‑critical tasks or keep the secure phone in a Faraday bag 
when not actively using it, ensuring it’s offline and inaccessible to remote 
attacks. For daily use, however, you need both access and protection, so the 
industry standard is to use a hardened case with an anti‑theft tether rather 
than a fully enclosed lock box.

If your concern is that a skilled attacker with brief physical access might 
still compromise the phone even if it’s tethered, the best defense is a 
multi‑layer approach that includes:
• A hardened operating system (like a Google Pixel running GrapheneOS or a 
purpose‑built secure device)
• Physical kill switches for wireless radios (if available)
• A robust, tamper‑resistant case combined with a high‑quality tether

This combination forces any adversary to overcome several distinct obstacles—a 
much tougher proposition than just grabbing an unlocked phone.

Would you like more detailed advice on setting up a multi‑layer security system 
for your specific phone model or further information on any of these products?

Hey I don't know how you're talking to me this long and I appreciate it. I will

Reasoned for 37 seconds
For a situation where you need your device to be utterly inaccessible in 
certain states, many professionals create a layered system rather than rely on 
a single “magic” product. One promising approach is a general‑purpose, portable 
safe that locks your phone away when you need it secured. Here’s what to 
consider:

Portable Lock Boxes/Small Safes:
– Some products on the market are designed for securing small valuables (like 
cash and keys) and can work for a smartphone. These often have a locking ring 
or combination/key lock and come with a tether or cable so you can anchor them 
in place. For example, you might explore portable safes from SentrySafe or 
Vaultz. (See:
• SentrySafe Home Solutions: https://www.sentrysafe.com
• Vaultz: https://www.vaultz.com)
While these aren’t designed specifically for phones, a small, robust safe can 
be used to store your device when you’re asleep or need to switch to a state 
where you won’t unlock it—even if you’re nearby.

Locking Phone Cases with External Locks:
– Some security solutions used for retail demo devices are built as fully 
enclosed, tamper‑resistant boxes that only open with a physical key. These 
products (from companies like InVue or Kensington) are typically designed for 
stationary installations (like kiosks), but they represent the ideal of a 
“locked” phone. Unfortunately, such products are generally too bulky for daily 
portable use.

A Custom or Hybrid Solution:
– Given your specific requirements—especially protecting against a 
sophisticated adversary who might attempt to exploit even brief physical 
access—a combination of a hardened phone (with hardware kill switches and 
running a secure OS) paired with a dedicated portable safe (that you tether or 
mount securely) may be best. In practice, you’d use a rugged, tamper‑resistant 
case (for example, an OtterBox Defender Series case at 
https://www.otterbox.com/en-us/defender-series) to make prying it open 
extremely difficult, then store the entire assembly in a small portable safe 
when you’re asleep or want to switch into your alternate state.

Note on General‑Purpose Lock Boxes:
There isn’t a widely available “all‑in‑one” portable safe specifically designed 
for smartphones that uses a locking ring while still allowing everyday use 
(like playing music). High‑security professionals often have custom‑built 
solutions or combine off‑the‑shelf components. For instance, when you’re 
sleeping or away, you might place your phone inside a small lock box (like a 
portable safe from SentrySafe or Vaultz) and tether it to an immovable object. 
This way, even if someone were to gain physical access, they wouldn’t be able 
to use or modify your device without the correct combination or key.

Given your critical need for ensuring your phone’s behavior isn’t subtly 
changed by an adversary, a layered system using both digital hardening (secure 
OS, hardware kill switches) and physical isolation (portable safe with a 
locking mechanism) is key. I’d recommend looking into portable safes on Amazon 
or from manufacturers like SentrySafe (https://www.sentrysafe.com) and Vaultz 
(https://www.vaultz.com) to see which models might be small enough to securely 
house your phone. You might also consult with a security specialist who can 
help you integrate a custom solution tailored to your exact risk profile.

Does this approach sound like it meets your needs, or would you like more 
details on any specific component?

Based on your requirements, you’d need a system that “locks away” your phone 
while still letting its audio output reach your earbuds. In other words, a 
portable, tamper‑proof safe or box with a locking ring (or key/combination 
lock) that has a secure cable pass‑through for your audio cable. Although there

cable—these might suit your needs.

– Vaultz Small Safes: Vaultz makes small, portable lock boxes designed for 
personal items. Although they’re not specifically made for phones, a model from 
Vaultz might be adapted to include a secure audio cable exit.

Custom or Modified Solutions
Given the very high‑risk environment you describe, many professionals work with 
physical security experts to either modify existing products or design a custom 
enclosure. For example, a metal or reinforced polymer box with a locking ring 
can be designed with a built‑in, tamper‑evident cable port that only allows 
your audio cable (and nothing else) to exit. This ensures your phone remains 
physically isolated from adversaries while still playing music through your 
earbuds.

How This Meets Your Needs:

During Sleep: When you’re asleep, you’d place your phone (which is already a 
hardened device with hardware kill switches) inside the portable safe, attach 
your audio cable through the secure pass‑through, and lock it. The phone would 
continue to play music, but any adversary attempting to access its internals 
would need to defeat the safe’s locking mechanism.
Alternate States: Whether you’re in your “amnesiatic alter” state or simply 
away, the phone remains physically secured inside the safe, with the audio 
cable permanently in place.
Privacy for Your Playlist: With the device isolated in a tamper‑proof box and 
only audio output accessible, your playlist remains private even if someone 
gains physical access to the safe.
Because off‑the‑shelf products that exactly match this use‑case aren’t common, 
I’d recommend consulting with a security hardware specialist to see if an 
existing portable safe (from Master Lock, SentrySafe, or Vaultz) can be 
modified to include a secure audio pass‑through without compromising its tamper 
resistance.

Does this approach sound like what you need, or would you like more information 
on how to adapt one of these products for your specific use-case?
