Check how strong your password is: score from very weak to strong, entropy estimate and 6 security checks. 100% local.
Type a password and watch the score update live: length, character variety, patterns, common passwords and estimated entropy bits. Everything is evaluated locally — nothing is sent anywhere.
Everything runs entirely in your browser. Nothing you type is ever sent to any server or stored.
A measure of unpredictability in bits. Each bit doubles the guesses needed: 50+ bits is reasonable, 80+ is strong.
Every extra character multiplies the combinations exponentially, far more than adding symbols does.
A list of the most breached passwords (password, 123456, qwerty…) is checked locally.
No — the check runs entirely in your browser. Nothing is transmitted.
12+ characters mixing cases, numbers and symbols, without patterns like aaa or 123.
Yes, completely free with no account.
