Multifactor Authentication (MFA, 2FA)
Multifactor Authentication (MFA, 2FA) is a method of confirming a user’s identity with two or more pieces (mobile app) of evidence when signing on to a system or a service. It means that you have a second way of confirming who you are when signing into a system or service, in addition to your username and password.
Multifactor authentication helps keep Aalto University services and data safe ensuring that only authorised persons have access to them. Username and password are not enough for authentication in a time of cyber attacks.
When you are working outside of the Aalto network, part of our services require multifactor authentication when you are signing in. The main method for multifactor authentication (MFA) at Aalto University is Microsoft Authenticator.
Are you already using MFA and are looking for instructions on how to use it? See How to use MFA.
MFA services use two or more authentication methods, as 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 organisations around the world and can be considered a standard.
How to begin using MFA?
