Why Use a Password Generator?
Humans are terrible at creating random passwords. We reuse passwords, pick dictionary words, and follow predictable patterns. A password generator uses cryptographically secure randomness to create passwords that are truly unpredictable — the single best defence against brute-force and credential-stuffing attacks.
3 Generation Modes
Random Password
Mix of uppercase, lowercase, digits, and symbols. Strongest option.
Passphrase
Multiple random words. Easy to remember, hard to crack.
PIN Code
Numeric-only. For devices, banking, 2FA.
Strength Levels
| Level | Entropy (bits) | Use Case |
|---|---|---|
| Weak | < 40 | Avoid — easily cracked |
| Fair | 40–59 | Low-value accounts only |
| Good | 60–79 | General web accounts |
| Strong | 80–127 | Email, banking, important accounts |
| Very Strong | 128+ | Master passwords, encryption keys |
Best Practices
- Use a unique password for every account.
- Use a password manager to store them.
- Aim for 80+ bits of entropy for important accounts.
- Enable two-factor authentication (2FA) wherever possible.
