Your Password Needs a Partner!

Strong passwords are essential, but they aren't enough. Phishing attacks and data breaches put all your passwords at risk, and you need additional security. With two-factor authentication, anyone trying to access your account must provide two proofs of ID:

  • Something you know, such as your password.
  • Something you have, such as a passcode, a phone, or even a mobile app.

Some services and websites refer to this as two-step authentication, two-step verification, or login verification.
