The last password you'll have to think about.
Create a strong, truly random password in one click — then check how safe your current ones really are. Everything happens in your browser. No logins, no tracking, nothing sent anywhere.
Everything runs in your browser — nothing is sent anywhere. Close the tab and the password is gone for good.
How long does it take to crack a password?
A short password falls instantly, however random it looks. The table and chart below model an offline attack at 10,000,000,000 guesses per second against a fast hash — the same maths a cracking rig actually runs.
| Password pattern | Time to crack | Entropy (bits) | Verdict |
|---|---|---|---|
| 6 lowercase letters | instantly | 28.2 | Weak |
| 8 lowercase letters | 21 seconds | 37.6 | Weak |
| 8 letters + numbers | 6 hours | 47.6 | Moderate |
| 10 mixed characters | 190 years | 65.7 | Moderate |
| 12 mixed characters | 2 million years | 78.8 | Strong |
| 6-word passphrase | 701 thousand years | 77.5 | Strong |
Assumes uniform random characters and no rate limiting. Password reuse or a breach database shortcut all of the above — which is why a unique password per account matters more than length alone.

Frequently asked questions
Is the Best Password Generator really free?
Yes — completely free, with no account, paywall or limits. Generate and check as many passwords as you need.
Are my passwords sent to a server?
No. Every password is generated and analysed inside your own browser using the Web Crypto API. Nothing is transmitted, logged or stored. Close the tab and it's gone.
How long should a password be?
Aim for at least 16 characters, and 20+ for important accounts. Length matters more than swapping a letter for a symbol. Our blog goes deeper.
What does the analyser actually check?
It estimates entropy (in bits), an offline time-to-crack, and flags weak patterns like common passwords, sequences and repeats. See the analyser.
