Text messages to a mobile phone

Apple Mail and Gmail users: remove and reinstall your University email account

If you use Apple Mail (on desktop or mobile devices) or the Gmail app to receive your University email, you'll need to remove your University email account from your app and reinstall it after you've set up multi-factor authentication.

For instructions on how to add and remove email accounts:

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.
  • Select 'United Kingdom' in the 'Select your country or region' menu and enter your mobile phone number in the box next to it.
  • Ensure 'Send me a code by text message' is selected in the 'Method' box, and click 'Next'.

You'll receive a text message containing a six-digit number from 'Microsoft' on your mobile phone:

Enter this number in the box on the 'Step 2' screen, and click 'Verify':

Set up screen 3

You'll see a reminder that some older applications don't support modern authentication by phone. In the unlikely event you encounter this issue, you'll be able to set up a separate 'app password' for those applications later. Click 'Finished' to complete the set-up process.

Set up screen 4

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 using your second factor. If you've set up this as your preferred method, you'll be sent a new code via text message to your chosen phone and see a prompt to enter the code on the login screen:

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!
