Password Strength Checker
See how strong a password is, how long it takes to crack and why, without it ever leaving your browser
The strength is an estimate from the patterns attackers try first, with the page's own lists of common passwords and words. It isn't checked against breached password databases.
How to check a password's strength
- Type the password; it stays hidden unless you show it.
- See its strength, and how long it would take to crack in four kinds of attack.
- Read what was found in it (common passwords, words, sequences, keyboard runs, dates) and how to make it stronger.
Questions
Is it safe to type my password here?
Yes, it's checked in your browser as you type and never sent anywhere. You can still check a password that's similar to yours.
How is the strength worked out?
It's an estimate from the patterns attackers try first: common passwords, dictionary words, names, dates, sequences like 1234 and keyboard runs like qwerty.
Does it check if my password was leaked?
No, that needs a service on the internet with the breached password databases, and the password never leaves your device here.
What makes a password strong?
Length and randomness: a long password or passphrase made by a generator, used for one account only.
