What servers do you have? Dell ones have iDRAC and HP ones have LOM
(Lights out management)
It allows access to power on/off the OS like you were pressing the
power button, and also access to the console like VNC, but it allows
you to see BIOS boot up messages also.
So, what I am trying to say, is your server might already have the
features you are asking for.
You can also add PDUs and UPSs that are controllable over TCP/IP if
you need them.

Kind Regards

James

Anything by APC.  It's perfectly normal and reasonable to have remote 
control power.

It puts all of your eggs in one basket, but you can do that in a 
browser, or perhaps in a password manager like Bitwarden

Subject: [GLLUG] Two factor authentication
Hi all,
I am thinking of deploying two factor authentication on our servers, but 
some of the other admins cannot get a mobile signal when they are at 
home. Is there any other way I can do this, or a better way of improving 
authentication?

[GLLUG] Power control over IP

[stuart taylor via GLLUG]

Hi all,

During the past 15 months I have managed to change various things involving our 
systems, for the better I think. We have also gained various part time 
volunteer admins, who are very good, mostly better than I am. One of them 
showed me how he could power down his servers remotely over IP, and restart 
them again. This looks very useful as we are spending less time at the building 
and mostly working from home. I have previously managed to obtain a cabinet, 
for our servers, change the lock for a padlock based system and restrict the 
key holders to a few people. This means switching servers on, or off, is better 
controlled, but also makes it more difficult for the admins to reboot when they 
are at home. Can anyone point me towards a suitable 'power supply over IP' 
solution? Are there any drawbacks to using these?

The only multi-factor authentication method I am aware of that
requires a mobile signal is SMS, and that is a really poor MFA
method.

Notably a TOTP solution doesn't need any network access except at
the initial setup time when the service tells you your key. Which
even that could be avoided if you did it by post or something!

Here's an example of an open source TOTP with PAM support which
works in any client that supports TOTP (not tied to Google in any
way):
