Multi Factor Authentication (MFA)

Office 365 Multi Factor authentication (MFA) provides additional security for your user account. MFA is a method of verifying who you are that requires more than just a username and password. Sign in can only be completed once you have acknowledged a sign in verification process either by text message, voice call or via a smartphone authenticator app. 


1. Why do I need MFA? 

Cybercrime continues to rise and as a result it is increasingly important that your personal information and data is protected. MFA uses a widely utilised security tool to help you authenticate who you are during a sign in process and keep personal and FX Plus data secure. This all operates on the same principle as when you receive a code by text to use your bank or have to approve the card you use when shopping online. Using an additional security method as part of MFA simply makes it that much harder for anyone to infiltrate your account. 

2. I'm having problems connecting to My Timetable (My Day) in the student app and portal and/or am not receiving email alerts from My Timetable 

Log into and select services or launch the app.

Disconnect both of the services (below) 

Return to the home page and click mail and timetable buttons to reconnect them both.

If you see an alert when accessing 'My Timetable', it will need to be approved via the bell icon. 

3. I am concerned about using my mobile phone for work/study purposes 

Keeping your account secure will protect both the organisation and your own personal data.  Your personal mobile phone details are not used for any other purpose than protecting your account. By adding the Microsoft Authenticator App to your personal phone this is just providing a method to confirm who you are.  The app is not used to manage or control your phone or provide any personal data.  

You must select at least one additional security method to your password, however, if you cannot, or do not wish to use your personal mobile, there are some other options available.  

You can use any land line number as an additional method. For example, you can use your home phone number. 

4. I have replaced my phone and need to reconfigure the MFA App

If you still have access to your old phone or a second method of MFA configured

• Go to you MFA dashboard here

• Click Add method

• Select Authenticator app and follow the process to add your new device

• Make your new device the default option – Microsoft Authenticator – notification

• Delete your old device

If you no longer have access to your old phone app or backup phone number, please contact the Service Desk. IT will reset your MFA settings and you can then complete the setup process. 

5. How often will I have to provide MFA verification?  

Once you have performed an MFA authentication you should not be prompted again unless you change your password. If you clear your browser cookies, use a different browser or use a private browsing window you will have to perform MFA again to verify your identity. If you keep being asked to provide MFA verification, please speak with the IT Service Desk. 

6. I've lost access to my phone and cannot access my account, what should I do?  

If you have lost access to the app and the backup phone number, please contact the IT Service Desk. IT will be able to reset your MFA settings. 

7. Can I use a third party MFA application (e.g. Google authenticator, Authy)? 

Most authenticator applications can be used. However, push notifications (a message that pops up on your mobile device) are only supported with the Microsoft Authenticator app.   

To add a third-party app complete the following steps:  

  • •Go to your MFA dashboard here   
  • •Click Add method  
  • •Select Authenticator app  
  • •Click Add  
  • •Click "I want to use a different authenticator app" and then follow the onscreen instructions.  

8. I’m having issues configuring the Authenticator App 

Try using text message verification as a workaround. If you continue to have issues, please speak to the IT Service Desk.  

9. How can I change my MFA settings?  

Go to and sign in to change your verification options at any time.  

10. What do I do if I’m offline?  

The Authenticator app enables you to generate MFA codes completely offline without access to the internet. This is ideal if you are abroad and concerned about data roaming costs.  

For more information about the Microsoft Authenticator app, please see here  

11. Where can I find further help and information on MFA? 

Below are some links to additional guides provided by Microsoft which you may find helpful.
