Multi-Factor Authentication (MFA)

Configuration Guide

MFA adds an extra layer of protection to ensure the security of online accounts beyond just a username and password. 

MFA is a valuable tool that protects against accounts with compromised passwords from being exploited by hackers. It will be enforced on the Microsoft 365 logins for all LSE users (staff and students) during the 2019-20 session. 

The principle behind MFA is to add an additional factor to the login process which makes it difficult someone else to login. In addition to a password (something you know) this MFA system will add something you have (your phone). [Other MFA systems may use something you are such as fingerprint, iris scan or face recognition]. 

You can use enable or request to reset your MFA settings for your LSE Microsoft 365 account here.

Once MFA is enabled on your account you will need to configure your phone based second factor of authentication. This can be a mobile app, a text message or telephone call to grant access. You can configure more than one of these options, and we recommend doing so.

Quick start using the app:

  • Fill in the form to request MFA here and wait for your confirmation email from DTS
  • From your phone, download the Microsoft Authenticator app for AndroidiOS or Windows Phone
  • Open this link from your computer browser and follow the instructions to sign in and configure your new settings
  • (After MFA is setup, this link takes you to your Microsoft 365 home page.)

For detailed instructions for setting up the app see MFA Instructions for  Mobile App

To set up a phone option see the MFA Instructions for Phone texts and calls.

Once configured, you'll be asked to sign in on other devices or web browsers the first time you use them. Don't worry, you won't be asked to repeat this every time you check your email on your phone or tablet (for instance), just once to confirm it is a safe device.

Please note once MFA is enabled some apps accessing Microsoft Office 365 based services (email, SharePoint, Teams) on your desktop and/or mobile device may need to be reconfigured.
