How Strong Is Your Password?
Test it instantly and privately – the checker runs entirely in your browser and estimates real-world cracking time, then tells you exactly what to fix.

Everything runs in your browser. Nothing you type is sent, stored or logged anywhere - you can disconnect from the internet and this tool still works. Still, test a password similar to yours rather than your real one.
What Actually Makes a Password Strong
- Length beats complexity. A 16-character phrase of random words beats P@ssw0rd! by thousands of years of cracking time.
- Unique per site. Most account takeovers reuse passwords leaked from another site – strength does not help if it is reused.
- Random beats memorable patterns. Keyboard walks (qwerty), years, and name+number combos are in every cracking dictionary.
The Practical Fix: Three Steps
- Install a password manager and let it generate 20-character random passwords for every account.
- Memorise just two strong passphrases: your computer login and the manager’s master password (4-5 random words).
- Turn on two-factor authentication for email, banking and anything with a card on file – it stops attacks even when a password leaks.
