Strong Random Password Generator

Free Strong Random Password Generator

Generate cryptographically random passwords that resist brute-force and dictionary attacks. Customise length, character classes (uppercase, lowercase, numbers, symbols), and exclude confusing characters (0/O, 1/l/I) for easier typing on mobile devices.

Features

• Length 8–64 characters — defaults to 16 (recommended for most accounts).

• Toggle character classes — uppercase, lowercase, numbers, symbols.

• Exclude lookalikes — drop 0/O/o, 1/l/I to reduce typing errors.

• Strength meter — visual feedback on entropy and crack resistance.

• Bulk generation — generate up to 100 passwords at once for a team setup or password rotation.

• One-click copy — copy to clipboard without showing the password on screen.

Password Best Practices

1. Never reuse passwords across sites — one breach can compromise every account.

2. Use 16+ characters with mixed classes for any account holding sensitive data.

3. Don't use personal data — names, birthdays, addresses, phone numbers are easily guessed.

4. Store in a password manager — Bitwarden, 1Password, KeePass — never in a spreadsheet.

5. Enable two-factor authentication wherever it's offered.

6. Rotate passwords after any breach notification or every 12 months for high-value accounts.

Privacy

Passwords are generated locally using the Web Crypto API — they are never sent to any server, never logged, and never stored. Open DevTools and check the Network tab: zero requests fire when you generate a password.
