Passwords are not the way to solve this problem except in the hopefully very rare case of catastrophe recovery. 'We believe in strong cryptography and reviewed code' The problem with passwords is that a human cannot be expected to remember any piece of information that is secure enough to be unguessable. Remember when the requirement to have mixed case and a punctuation mark in a password came in? That was in response to Crack published in 1991 which was a dictionary based search running on machines that could do 35 password tests a second. Four years ago, someone lashed together 20 GPU cards discarded by the bitcoin miners and built a machine that could do 350 billion tests a second. It isn't a dictionary attack and so the password restrictions actually reduce the search space and make the problem easier. Passwords are done, they are dead. If we want to have an application configuration protocol it should be capable of configuring cryptographic authentication credentials. Now we might optionally encrypt those credentials with a PIN, but that is a local security matter, not something that travels over the network.
