Free Online Secure Password Generator

1. Drag the length slider to the password length you need (16+ recommended).
2. Pick the character classes — upper, lower, digits, symbols.
3. Optionally enable Exclude ambiguous or customise the symbol set.
4. Click Generate. Check the entropy preview, then copy the result.

This generator uses `crypto.getRandomValues` — the browser's cryptographically secure random source, the same one used to seed TLS session keys — for every character draw. Each character is independent and uniform across whichever character classes you've enabled, and the entropy display shows exactly how many bits of unpredictability the result carries.

A good rule of thumb: aim for at least 80 bits of entropy for a typical account and 128 bits for a high-value one (banking, primary email, password-manager master password). Sixteen random characters drawn from upper + lower + digits + symbols clears 100 bits comfortably. Excluding ambiguous characters (0/O, 1/l/I) makes the password easier to type back from a phone screen or printed page at a small cost in entropy.

Generated passwords are not stored anywhere — close the tab and the history is gone. The right place to keep a generated password is a password manager (Bitwarden, 1Password, KeePass), not a text file or sticky note. Never reuse a password across sites.
