Sign-in via an alternative method

If you have more than one method registered for TSSI (for example both phone text code and Microsoft Authenticator app), the method first offered to you if prompted to complete TSSI as you log into your account will be the one Microsoft considers the most secure option. If one of your registered methods is the Microsoft Authenticator app, Microsoft will always first prompt you to verify your identity with the app when you log into your account.

If you are unable to complete TSSI with the Microsoft Authenticator app, click on the link “I can't use my Microsoft Authenticator app right now” available at the bottom of the “Approve sign in request” screen, which will bring you to a screen with your alternative methods of verifying your identity.

2. Click on your profile icon at the top right. Then choose View account.

   

3. From the left menu, choose Security info.
4. Then click the Delete link next to the app password you want to remove.

   

What will I see when using Two Step Sign-In

You will see a request screen pop up during sign-in.

Depending on the type of verification you will then receive either a:

• Text message, that contains a verification code, to your phone
• Phone call asking you to verify via your phone keypad
• Push notification from the Microsoft Authenticator app to your phone asking you to enter a matching number that is shown on your computer screen
• Push notification from the Microsoft Authenticator app to your phone asking you to 'Approve' or 'Deny'. This option will only show if you are using the staff VPN service.
• One-time password code from the Microsoft Authenticator app. This code should be entered into the request window on your computer

Please see the below sections for examples of what each option may look like.

Verifying via text message

Once you receive a text message to your phone with a verification code, paste this code into the request window and click Verify

Verifying via phone call

Once you receive the phone call, answer the call and press the # key to complete the process. You can then hang up.

Verifying via Microsoft Authenticator app

There are three ways in which you can be asked to verify via the Authenticator app.

Number matching push notification

A number will be shown on your computer and you will asked to enter the same number in app.

'Approve' or 'Deny' push notification

An 'Approve' or 'Deny' notification will be show on the app.

This option will only show if you are using the staff VPN service.

One-time password code

You will be asked to enter a one-time password code from the app into the sign in window on the computer. The one-time password code can found in the app by clicking on the email address associated with the account.

Using the 'Don't ask again for 30 days' option

During the two step verification process you can choose the option 'Don't ask again for 30 days' or 'Stay Signed in?'

Only use these options on a secure device that only you can access.

Selecting these options will save your login details, on the device (computer/tablet/phone) you are currently using, and you won't be asked to login/verify again for 30 days on that device.

After 30 days you will need to complete the two step login process again.
