Password Generator — Tutorial
Password security basics
Strong, random passwords are your first line of defense against cyber attacks. Weak passwords can be cracked in seconds, while strong ones could take billions of years.
What makes a password strong?
- Length: Longer passwords are exponentially harder to crack. Aim for at least 12 characters.
- Character diversity: Mix uppercase, lowercase, numbers, and symbols
- Unpredictability: Avoid dictionary words, personal information, or common patterns
- Uniqueness: Use different passwords for each account
Password strength examples
- Weak:
password123- Common word + predictable numbers - Better:
P@ssw0rd123!- Some complexity but still predictable - Strong:
K#9mQ$vR2@pX8wL- Random characters, good length - Memorable:
coffee-mountain-happy-42- Random words with separator
Password security guidelines
- NIST SP 800-63B: Recommends 8+ character minimum, no regular changes
- Use a password manager: Store unique passwords for every account
- Enable 2FA: Add two-factor authentication where possible
- Check for breaches: Use services like Have I Been Pwned
