[$] Adding a "duress" password with PAM Duress

Users often store a lot of sensitive information on their computers-fromcredentials to banned texts to family photos-that they might normally expect to be protected by the login password of their account. Under somecircumstances, though, users can be required to log into their system sothat some third party (e.g. government agent) can examine and potentiallycopy said data. A new project, PAM Duress, provides a wayto add other passwords to an account, each with its own behavior, whichmight be a way to avoid granting full access to the system, though thelegality is in question.
