Use a Mobile Number as an Authentication Method

After you enroll your mobile device as a 2–Step Verification method, use it to provide a second method of verification when you log in.

1. Enter your user name and password in an MFA-protected environment.
   The Mobile Number Verification page appears, with a message saying that a passcode was sent to your mobile number.
2. Get the passcode from your mobile device and enter it into the Passcode box.
   If you didn’t receive the passcode, click Resend Passcode.
3. (Optional) Select the Trust this computer for _ days check box (if enabled by your administrator) to skip providing a second method of authentication for the number of days indicated when you log in from the same device. The number of days is defined by your administrator.
4. Click Verify.
5. (Optional) If you can’t receive a text, for example, you don’t have your phone with you, click Show alternative login methods to use an alternative method to verify your identity.

   Note:

   You must have previously set up more than one verification method, such as using a bypass code that you previously generated and stored in a safe place. If you haven’t set up more than one verification method, you can call the help desk and have a bypass code generated for you.
6. (Optional) You can also select Show alternative login methods to change your default verification method.
   1. Click Show alternative login methods. All 2–Step Verification methods that you are enrolled in appear in the Alternative login methods section.
   2. Select a different verification method. You are then prompted to enter the required verification for that method.
   3. Enter the required verification.
   4. Select the Make this my default method check box to set this 2-Step Verification method as your default. The next time that you log in, you are prompted to verify your identity using this method of verification.
