Using the encryption key, it states that it's a One Time Configuration and cannot be changed later. My question is, can it be deleted to allow the users to create another password and to re-enter their personal accounts?
Option 1: Use my encryption key and do not store it (recommended)
All your passwords will be encrypted using the key supplied by you and the key will not
be stored in the PMP database. To access your personal passwords you will have to
supply this key every time and if you forget this key you will lose all your passwords.
