Calls to a landline or mobile phone

Video tutorial



Make sure you're signed out of your Microsoft account on other desktop applications, such as Microsoft Teams, Office applications and other browser windows before you proceed.

In the 'Step 1' of the 'Additional security verification' screen:

  • Select 'Authentication phone' from the first drop-down menu. Please don't select the 'Office phone' option – University staff have found that this doesn't work. You can still use your work landline number in the next step.
  • Select 'United Kingdom' in the 'Select your country or region' drop-down menu and enter your chosen phone number in the box next to it.
  • Ensure 'Call me' is selected in the 'Method' box, and click 'Next'.

Phone step 1

You'll receive an automated call from the Microsoft Sign-In Verification Service on your chosen phone. Confirm the phone number to be registered by pressing the '#' key on your phone keypad.

Phone call step 2

Complete the login process by selecting whether to stay signed in. Select 'No' if you're on a public computer.

Set up screen 5

The next time you log in to a Microsoft application such as Outlook, you may be asked to authenticate with a second factor. If you have chosen this as your preferred method, you'll receive an automated call to the number you've registered.

As before, press '#' on your phone keypad to complete the authentication. Note that the recorded message will refer to this as the 'pound sign'.

Signing into Teams

The next time you use the Teams desktop app, make sure you're signed in. Look out for a thin notification banner at the top of the application window that asks you to sign in – it's easy to miss!
