Aalto Multifactor Authentication on Office 365 accounts

Multifactor Authentication (MFA, 2FA) is a method of confirming user’s identity with two or more pieces (mobile app) 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.      

Mobile      

  • Download and install Microsoft Authenticator app from your mobile store. (remember to accept notifications sent by the app!).
  • Note! Do not sign in to the Microsoft Authenticator app.

Mobile/Workstation

  • Go to https://aka.ms/mfasetup for MFA.
  • Sign in with your Aalto email address.
    • If you don´t have an Aalto email address, enter your Aalto account in this format [email protected] and choose "Next" and sign in with your Aalto account in this format aalto\aaltousername and type your Aalto password. Choose "Sign in"
  • Follow the instructions on the screen. 

NOTE! When MFA registration is mandatory for your organisation, you can postpone the registration for 14 days, if you are not able to do the registration at that very moment.
