CONTROLLED USER ACCOUNT ACCESS WITH AUTOMATICALLY REVOCABLE TEMPORARY PASSWORD

Systems and computer-implemented methods are disclosed for providing controller access to a normally single-user account. In an example system, a primary user is provided with a primary password to the user account. A secondary user may be temporarily authorized by generating a temporary password selected independently of the primary password. The user account may be accessed by entering either the primary password or the temporary password. The temporary password is automatically revoked in response to granting access with the primary password. The secondary user is thereby provided with temporary access to the user account that is revocable by the primary user at any time without having to share the primary password with the secondary user and without having to change the primary password.
