Strong passwords, generated locally
Reused and guessable passwords are the leading cause of account takeovers. A long, random password generator result — different for every account — is the single best habit you can adopt. This tool builds one in your browser using cryptographic randomness, then shows exactly how strong it is.
How to use it
- Pick a length — longer is stronger. 20+ is a great default.
- Choose which character sets to include.
- Optionally exclude look-alike characters for easy transcription.
- Copy it, then store it in a password manager.
What “entropy” means
The bits figure estimates how hard the password is to guess. Each extra bit doubles the work an attacker faces. Aim for 80+ bits for everyday accounts and 128+ for anything critical.
