Two-step Login

With two-step login, anyone trying to access your account must provide two forms 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, multifactor authentication, or login verification.

The difference between the "normal" OSU login screen and the two-step login screen is shown here.
