There is no panacea. Biometrics can have revocation issues.

Yep. Biometrics-only or biometrics in conjunction with a PIN/password are 
really the best way to go. We *have* the technology to do this.

I still think passwords have to die.  There are better options.

Subject: Why not failwords?

I was just reading all those emails about making hard to crack passwords 
(Almost but not quite OT: Passwords). I like Steve Gibson’s analysis of why 
long passwords are harder to brute force crack than shorter complex ones. But, 
I wonder…

Why hasn’t anyone implemented fail words? Two or more passwords associated with 
your account or whatever. One you use for normal access and is as hard to crack 
as you can make it and still be memorable. Then another password that would be 
easy(er) to crack that triggers some event? Here are a few scenarios I can 
think of off the top of my head:

[] Bank manager forced to open the vault at gunpoint. Use the failword. Opens 
the vault and rings the silent alarm.
[] Someone tries to login to your PayPal or bank account and tries your 
failword. They get the usual bad password result, but you get a text message on 
your cell phone.
[] Someone tries to unlock your iPhone. They try the failword and it gets 
locked until you send it a special email or text or 24 hours expire, etc. 

Is there some reason this is a bad idea? I can’t think of any…
