US Patent 9154497 Maintaining accountability of a shared password among multiple users

A network server verifies a requesting user's permission to use a password to access a shared account hosted on a network server. The requesting user may be the person to whom the password was assigned, or in some cases, permission to use the password may have been granted to the requesting user by the person to whom the password is assigned. Provided the requesting user has permission to use the password, the system authenticates the requesting user for access to the shared account, and maintains accountability of the password.
