Does not compute. If there is a mechanism by which you can authenticate, you can be coerced into authenticating through that method.
The paper covers this of course:
>Coercion detection. Since our aim is to prevent users
from effectively transmitting the ability to authenticate
to others, there remains an attack where an adversary
coerces a user to authenticate while they are under adversary control. It is possible to reduce the effectiveness of this technique if the system could detect if the
user is under duress.
I take issue with the the article suggesting it's completely resistant to coercion. A system that detects duress... interesting I guess but seems like a stretch.

Really? Playing around with KeePass briefly, it seems this is comparable to a 6 character password that includes upper, lower, numeric, and special characters. I wouldn't consider that very strong. Besides the fact that it appears you're not entering the password exactly, but only (if I'm understanding correctly) "good enough".
