Aalto Multifactor Authentication on Office 365 accounts

Multifactor Authentication (MFA) is a method of confirming user’s identity with two or more pieces of evidence when signing on to a system or a service.

Users can enhance security of Aalto Office 365 accounts by registering for multifactor authentication service. More information about multifactor authentication service can be found below.

Multifactor Authentication – What it is?

Multifactor Authentication (MFA) is a method of confirming user’s identity with two or more pieces of evidence when signing on to a system or a service.

MFA services use two or more authentication methods mentioned below:

  • Something you know (typically a password)
  • Something you have (a trusted device that is not easily duplicated, like a phone)
  • Something you are (biometrics)

Why Multifactor Authentication?

  • MFA brings an additional layer of security to your user account

In addition to the username and password, the attacker would need access to the extra authentication method you’ve defined.

  • MFA is already in use at organizations around the world and can be considered a standard

How to take MFA into use?

Register for the multifactor authentication service. You can do it on either mobile or your workstation.
