I think you read parent-comment wrong. My interpretation: unlock your phone normally at least every 12h. Only if you fail to do that, then the phone locks harder and you need to unlock with the non-memorizable password. Imagine the PIN/PUK system on SIM cards but with a timed lock-out as well. I agree that it sounds inconvenient though.

I'm not that familiar with the US law system, but wouldn't a written down password be worse? With a memorized password it's at least possible to claim you have forgotten.

Some encryption schemes allow two keys for unlocking, but they would show different content depending on the key. I think I remember trying that on TrueCrypt many years ago.

I would imagine the second password being in a safe in a Swiss bank.

It's not practical at all, but there should be possible to build systems that authenticate you only if you are free and doing that on your free will without any compulsion.

I sleep longer than 12h most days.
