Why is password security important?
Basic security rules:
- Separate password for each account: Compromising one password doesn't put others at risk
- 16+ character length: Longer passwords are mathematically harder to crack
- Various character types: Combination of letters, numbers and special characters
- Use password manager: Securely store all passwords
- Enable 2FA: Two-factor authentication provides additional protection
- Regular updates: Periodically change passwords for important accounts
Professional tips:
- Exclude similar characters (i, l, 1, L, o, 0, O)
- Don't use personal information (name, birth year)
- Don't use dictionary words directly
- Consider brute force attacks (120+ bit entropy)
- Memorable passwords are useful for easy recall
Recommendation: Strong passwords cannot be cracked by computers for 100+ years. This tool creates passwords that meet professional standards.
