About this tool

The Password Generator creates strong random passwords using a cryptographically secure source in your browser. Tune length, character sets, and ambiguity rules to fit any site’s password policy — then copy straight into your password manager.

How to use

  1. Pick the password length (16+ is recommended for most accounts).
  2. Toggle character sets: uppercase, lowercase, digits, symbols.
  3. Optionally exclude ambiguous characters like 0/O and 1/l/I.
  4. Click Generate and read the strength indicator.
  5. Copy the password and paste it into your password manager.

Common use cases

  • Creating a strong password for a new online account.
  • Rotating a leaked password.
  • Generating a random admin password during server setup.
  • Producing a Wi-Fi passphrase that is hard to guess but still copy-paste friendly.
  • Bulk-generating test passwords for QA accounts.

Frequently asked questions

Is the generator actually random?

Yes. It uses the browser Web Crypto API (crypto.getRandomValues), which is suitable for security purposes.

Should I memorize this password?

No. Store it in a password manager. Random passwords protect you precisely because they cannot be memorized.

Is my generated password logged anywhere?

No. Passwords are generated locally and never leave your device. Nothing is sent to a server.

Why exclude ambiguous characters?

Some characters look alike in common fonts. Excluding them helps when you must type the password manually.
