Summary
The Temporary Login Without Password WordPress plugin before 1.9.9 does not prevent a temporary user from creating an Application Password, and does not revoke one when the temporary access expires or is disabled, allowing the recipient of a temporary login to retain working access to the site over REST and XML-RPC after the administrator believes it has been withdrawn. The retained access carries whatever role was granted, which for the Temporary Login Without Password WordPress plugin before 1.9.9's main use case is Administrator.
