RoboForm Strength Evaluation

RoboForm calculates individual password strength using zxcvbn, a powerful open-source password strength estimator. Most password strength checkers merely count lowercase letters, uppercase letters, digits, and symbols (LUDS). They do not consider dictionary entries, common names, and known common passwords and their variants. This often causes them to rate poor passwords like ‘P@ssword1’ as strong incorrectly.

This tool uses JavaScript to check password strength on your device only (client side). These passwords are not transmitted to our servers.
