Abstract
Data storage devices, methods, and systems for passcode authentication based on automatically generated and dynamically changing unlock passcodes are described. An access controller of a data storage device is configured to receive a first passcode based on an externally generated input passcode that is synchronized with internal generation of an unlock passcode by the access controller. The access controller generates a second passcode based on the internally generated unlock passcode, and unlocking the data storage device is responsive to the first passcode matching the second passcode.
