Password Strength Checker
Test how strong your password is — 100% in your browser.
Type a password to instantly see how strong it is, roughly how long it would take to crack, and what to fix — all calculated in your browser.
Everything runs locally in your browser. Your password is never sent, stored, or logged anywhere.

Type a password and see how hard it is to guess: a 5-level rating, its entropy in bits and an estimated crack time, plus tips that flag common words, keyboard runs like qwerty and repeated characters. The check runs entirely in your browser, so the password is never sent or stored.
Frequently Asked Questions
Q. How does the checker rate a password?
A. It multiplies the length by the size of the character set you used (lowercase, uppercase, digits, symbols) to estimate entropy in bits, then subtracts for common passwords and words, repeated characters and runs like abc, 123 or qwerty. The result is shown on a 5-level scale from Very weak to Very strong.
Q. What does the estimated time to crack assume?
A. It is a worst case: an attacker who has stolen a fast hash such as MD5 and tries 10 billion guesses per second offline. Sites that use slow hashes like bcrypt or limit login attempts make a real attack far slower, so treat the figure as a relative guide, not a guarantee.
Q. Is it safe to type my real password here?
A. The check runs only in your browser: the password is not sent to a server, stored or logged, and it is not looked up in breach databases either. If you would rather not, test a password with the same structure instead.
