Password Strength Checker

Type a password to instantly see its strength based on length, character variety, and common criteria.

    Pourquoi utiliser cet outil ?

    A weak password is one of the most common security failures. This tool checks your password against standard strength criteria (length, uppercase/lowercase, digits, symbols) directly in your browser — your password is never sent anywhere, not even to check its strength.
