A strong password generator that picks characters cryptographically (Web Crypto API), in your browser only. The password never leaves your tab. You configure length, character classes and exclusions - the generator shows the entropy in bits and gives you a ready-to-copy string.
How to generate a password
- Set length with the slider - 12-16 chars is the minimum, 20+ for critical accounts.
- Pick character classes: lowercase, uppercase, numbers, symbols. More classes = more entropy.
- Optionally exclude lookalike characters (l, 1, I, O, 0) - useful if you will dictate or retype the password.
- Copy the password, save it in a password manager (1Password, Bitwarden, KeePassXC). Never store in plain text files.
- The generator keeps the last 5 passwords locally and never sends them - refresh the page to clear.
Use cases
New bank, email, social-media account. Password for a company tool with complexity requirements. Home Wi-Fi password (long, static). API key or service token. Anywhere your password manager suggests "generate new". If you prefer something memorable (for a master password you actually have to type), use the passphrase generator instead. For numeric-only codes (banking PINs, vault locks) try the PIN generator, and after you generate a password run it through the password leak check to make sure it has never appeared in a breach.
