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.
Why it's free
A discreet ad banner covers hosting costs — that's the whole business model. No account to create, no usage limit, no paid tier unlocking the real result. Calculations run in your browser, so your numbers, dates and text never leave your device.
