Password Security Best Practices

Length Matters Most
Longer passwords are exponentially harder to crack than complex short ones
Use Passphrases
Combine 4-6 random words: "correct horse battery staple"
Unique Passwords
Never reuse passwords across different accounts
Password Managers
Use a password manager to generate and store unique passwords
Two-Factor Authentication
Enable 2FA wherever possible for additional security
Avoid Personal Info
Don't use names, birthdays, or other personal information
Regular Updates
Change passwords if you suspect they've been compromised
Secure Storage
Never store passwords in plain text or unsecured locations
