Why should I switch on Multi-Factor Authentication on my university account?

Multi-Factor Authentication (MFA) is a way of confirming your identity with something you have, typically a phone. After entering your username and password, as usual, you can tap on a notification in a mobile app or receive a six-digit code via phone call or SMS text message. 

What is MFA?
MFA is a security system that requires more than one method of authentication from independent categories of credentials to verify your identity when signing in to certain services. Further information from Microsoft can be found in this short video:
Why should I switch it on?
One of the major challenges facing email users is 'phishing' emails, which are designed to steal user credentials, by configuring MFA on your account, you can decrease the possibility of, and prevent your credentials being stolen.
Will I have to use a second verification method every time I sign in?
No, when you get a pop up asking for your second factor there is a tick box you can select to have it remember the sign-in for 30 days. It is only recommended that you do this if you trust the device and will be using it again. This applies only to the application you are in so you may find that you have to do this for a couple of sign-ins on your device (MS Office, your browser and Teams for example) but after that, you should not have to verify your sign-in on that device until the next month.
