This article describes the steps to setup the Office phone method of authentication.
Step-by-step
The Office phone method allows to receive a call at your office phone that includes an extension. This is helpful for situations where you do not have a direct line to use with the Phone option.
Open up a browser and go to https://mysignins.microsoft.com/security-info.
Login using your SSD username and password.
Click the Add sign-in method button.
Select the Office phone method from the list. Click Add.
Enter your 10-digit number (no special characters. e.g., 3149898000) and extension. Click the Next button.
Answer the call and follow the prompts.
If you followed the prompts correctly, you will be prompted with a success screen. Click Done.
Now you may use this MFA option when logging into your SSD account.
