Multi-Factor Authentication (MFA)
Multi-Factor Authentication (MFA)
In 2020 Imperial will be making MFA compulsory on some sensitive services, such as Office365, and will roll it out to other services as the need arises. Their overview and reasoning is here: https://www.imperial.ac.uk/admin-services/ict/self-service/be-secure/mfa/
There's no need to repeat what they say, but it is universally accepted to be a good idea to enable MFA on personal communications and collaboration services.
How To Enable MFA on your Office365 Account
First of all, ICT have to provision your account for this feature - you can't just decide to turn it on yourself. You will get an email from the "ICT Security Officer" when MFA is ready to be enabled on your account. Once it has been provisioned for you, Imperial's instructions are here: https://www.imperial.ac.uk/admin-services/ict/self-service/be-secure/mfa/setup-mfa/
