Password Security Best Practices
- Length: At least 12 characters, 16+ recommended
- Complexity: Mix of uppercase, lowercase, numbers, symbols
- Hashing: Use bcrypt, Argon2, or scrypt for passwords
- Uniqueness: Never reuse passwords across sites
Note: This calculator assumes pure brute-force attack. Real-world attacks often use dictionaries and rainbow tables, which can crack weak passwords much faster. Always use strong, unique passwords.
