  • Password generation method and system
    Patent number: 6643784
    Abstract: A system and method employs a password rule data provider that provides password generation rule data to a notification device, such as visual display device or audible output device. A password data evaluator, such as a per character password data evaluator, continuously evaluates password character data as its being entered and compares each character to the password generation rule data. A dynamic status data generator dynamically generates password rule status data, such as visual indication of which rule has been met or which rule has not been met as password data is being entered.
