Password Security Basics
What Makes a Strong Password?
A strong password in 2025 should meet these criteria:

- Complexity: Mix of uppercase, lowercase, numbers, and symbols
- Uniqueness: Different for every account
- Unpredictability: Avoid personal information and common patterns

Advanced Security Techniques
Multi-Factor Authentication (MFA)
Even the strongest password can be compromised. Multi-factor authentication adds crucial additional layers of security:
SMS Authentication
Basic but better than nothing. Beware of SIM swapping attacks.
Authenticator Apps
Google Authenticator, Authy, or Microsoft Authenticator provide time-based codes.
Hardware Keys
YubiKey and similar devices offer the highest security level.
Password Passphrase Method
Consider using passphrases instead of traditional passwords. They're easier to remember and can be incredibly secure:
Passphrase Examples:
- Coffee-Sunset-Mountain-7483
- Purple#Elephant$Dances@2025
- MyFavorite!Book#Has247Pages
Common Mistakes to Avoid
Reusing Passwords
Using the same password across multiple sites means one breach compromises all your accounts.
Writing Passwords Down
Physical notes can be stolen or seen by others. Use a password manager instead.
Sharing via Email/Text
Never send passwords through insecure channels like email or text messages.
Never Updating
Old passwords should be changed regularly, especially after security breaches.
