Abstract

A radio frequency system and a password management method applied to a storage device of the radio frequency system are provided, in which a first access password is stored for deciding whether to permit access to information and a first changed password. The first changed password, a second access password, and a second changed password are received, and the first access password is changed to the second access password, and the first changed password is changed to the second changed password. Accordingly, information access authority in the storage device and a password change authority can be exclusively transferred according to the transfer of management of the storage device, and information leakage caused by a previous manager's password leakage or a third person's password leakage can be prevented.
