See how strong your password really is — and roughly how long it would take an attacker to crack it. Type or paste a password below. It never leaves your device: no uploading, no logging, no storing. Safe to test a real password.

Length is the biggest factor. Aim for at least 14–16 characters, mixing upper and lower case, numbers and symbols, and avoid real words, names, dates and common patterns. A random passphrase of several unrelated words is both strong and memorable.
The tool estimates the password's entropy from its length and character variety, then approximates how long a fast offline attacker (billions of guesses per second) would take. It's an estimate for guidance, not a guarantee.
A strong password can still be compromised in a data breach. Check your email at haveibeenpwned.com, and if it appears, change that password everywhere and turn on two-factor authentication.
