What is Multi-Factor Authentication (MFA)?

Multi-Factor Authentication (MFA) refers to an additional layer of security that is added to the login process.  Similar two step verification processes are already widely used by Banks; Mobile Phone Companies etc to provide an extra level of security for their customers.


MFA relies on two forms of authentication: something you know, and something you have with you. The something you know is your password. The something you have with you can be a mobile device. This means that even if your password is hacked, your account will remain secure. 


Learn more about Microsoft’s Multi-Factor Authentication on their Overview Page.

What if I don’t have my mobile device with me?

  • If you are on campus: you will be able to log in  - you will need to be connected to the University network without having to use MFA. 
  • If you are off-site and you have lost your device then please contact the ServiceDesk : 020 8392 6000 or ServiceDesk@roehampton.ac.uk.


What if I have changed my phone number/lost my phone and it is set up as my only authentication method?

 If you have lost your phone or you have changed your phone number and you are now not able to use MFA please contact the ServiceDesk.  You will need to provide the following:

  • Old phone number
  • The new phone number
  • Verification from your manager that you are the user


I have registered for MFA but now I cannot access my Roehampton emails on my mobile phone

 Once enrolled on MFA, you will no longer be able to use your native (built in) email client on your phone or tablet to access Roehampton emails.  You are therefore advised to set-up and use one of the following means of access to Roehampton emails before registering for MFA:


  • Microsoft Outlook app for IOS or Android (strongly recommended)
  • Use the web browser to access Outlook Web Access (OWA), i.e. Microsoft O365
