Generate strong random passwords. Choose length, symbols, numbers, and avoid lookalikes. Runs locally.

Strength: Empty

What it does

A free password generator that runs entirely in your browser — the password never leaves your device. Choose length (8–64), toggle character classes (lowercase, uppercase, digits, symbols), optionally exclude look-alike characters (I, l, 1, O, 0, o), and get a fresh strong password. A built-in strength meter estimates entropy based on the character pool and length.

Longer is better: a 20-character password with mixed classes has more entropy than a complicated 10-character one. For anything you actually care about — email, banking, password manager master password — aim for 16+ characters with all classes enabled. Paired with a password manager, you only need to remember one strong password ever.

How to use it

  1. Slide Length to your target (20 is a solid default).
  2. Toggle character classes — keep all four on unless a site blocks symbols.
  3. Click Regenerate until you get one you like.
  4. Click Copy and paste into your password manager or the signup form.
