Abstract
A data processing system-based password protection system protects a resource with an access password that may be user selected. The access password and an encryption key unique to the resource are stored in non-volatile storage at a data processing system, where the encryption key is at least partially derived from unique information associated with the resource. In response to receipt of an attempted access password at the data processing system, access to the resource is permitted if the attempted access password matches the stored access password. However, in response to an indication that the access password has been forgotten, an encrypted access password generated at the data processing system from the stored access password utilizing the encryption key is output from the data processing system. The access password can thereafter be recovered from the encrypted access password and the unique information.
