Recently I proposed a novel way of choosing and managing passwords in a secure way, especially suitable for the typical situation of a modern user with multiple accounts and frequent password changes on some of the accounts. The name I suggested for it is ?passwords with a random on-paper part?, shortened as PROPP. The PROPP method is also suitable for scenarios in which the user needs to log in on a wide and unpredictable range of devices, although in the description below I concentrate on a one-computer scenario.
