Understanding Password Entropy
Password entropy measures randomness and unpredictability. Higher entropy means stronger passwords. Our generator calculates entropy in bits, with 60+ bits considered strong for most purposes.
Security Best Practices
- Length Matters: Each additional character exponentially increases security
- Character Variety: Use uppercase, lowercase, numbers, and symbols
- Unique Passwords: Never reuse passwords across different accounts
- Regular Updates: Change passwords periodically, especially for sensitive accounts
Common Mistakes to Avoid
Avoid dictionary words, personal information, sequential characters, and common substitutions. These patterns make passwords predictable and vulnerable to attacks.
