Free Strong Password Generator — Secure Random Passwords
Generate strong, secure, random passwords instantly with custom options. All passwords are generated locally in your browser — never transmitted anywhere.
Why Use a Password Generator?
Strong passwords are your first line of defense against unauthorized access. A good password should be long, random, and unique for every account. Our generator creates cryptographically secure passwords using the Web Crypto API — the same standard used by banks and security software.
What Makes a Strong Password?
- Length: At least 12 characters. 16-20+ is better for sensitive accounts.
- Complexity: Mix of uppercase, lowercase, numbers, and symbols.
- Uniqueness: Never reuse passwords across different sites.
- Randomness: Avoid predictable patterns, names, or dictionary words.
Tips for Password Security
- Use a password manager (like Bitwarden or 1Password) to store your passwords.
- Enable two-factor authentication (2FA) wherever possible.
- Change passwords immediately if a service you use reports a data breach.
