Password Strength Checker

See how long it would actually take to crack a password, in your browser.

Password (never leaves your browser)

All analysis runs in your browser. The password is never sent anywhere.

Rule of thumb

Aim for 14+ characters using 4 random words (a passphrase) or a long random string from a password manager. Length matters more than fancy symbols.
