  • Random combination with no patterns

Uniqueness:

  • Different password for every account
  • No reusing or slight variations
  • Not based on personal information

  • Use authenticator apps, not SMS

Regular Updates:

  • Change passwords every 6-12 months
  • Immediately change if breach suspected
  • Update compromised passwords right away
  • Check haveibeenpwned.com for breaches

Common Password Mistakes

  • ❌ Using same password everywhere
  • ❌ Writing passwords on sticky notes
  • ❌ Sharing passwords with others
  • ❌ Using personal information (birthdays, names)
  • ❌ Saving passwords in browsers on public computers
  • ❌ Never changing passwords
  • ❌ Using simple patterns (123abc, abc123)
