Tips for Strong Passwords

  • 12+ characters (longer is better)
  • Mix uppercase + lowercase
  • Add numbers and symbols
  • Avoid names or birthdays
  • Use unique password per account

Use a Password Manager

Stop remembering passwords. Let a password manager create and store unique, strong passwords for you.
