Multi-Factor Authentication (MFA) helps safeguard access to data and applications. It provides additional security by requiring a second form of authentication and delivers strong authentication via a range of easy to use authentication methods

What Is It?

MFA adds another layer of security to your online accounts

Requires “two factor authentication” (2FA) to verify your identity when you log in to a service by:

- Something you know (such as your password)

- Something only you have (such as your mobile phone, on which you will receive a login confirmation notice via text or phone call)

Why Should I Do It?

Protects student and employee data from being compromised.

Increasingly, hackers have targeted higher education institutions by using hacked credentials to:

- Fraudulently acquire sensitive information, such as username, password and banking details

- Masquarade as you in an attempt to aquire sensitive information from others

What Are The Benefits?

MFA is the most effective way of stopping this type of fraud since you are notified and required to verify login to your account

MFA is essential to help safeguard access to critical systems

MFA provides much stronger insurance that your information is only accessible to the intended people, and that NUI Galways email systems and services remain available for students and staff



  • When setting up MFA for the first time, it is only possible to configue the Authenticator App if you have access to two devices. i.e. you cannot set up Outlook App on iPhone or Android for first time use on the same device that the Authenticator App is on.
  • A workaround to this would be to access Outlook via a browser session on your mobile device. MFA will see the Outlook browser session as 'One' device, in which case, it would be possible to configue the Authenticator App for first use (in which case, you will need to configure the Authenticator App using the 9 digit code and URL provided as opposed to the QR Code).
  • When accessing your mail account via Outlook on the Web (i.e. through a browser) you will be asked for secondary authentication each time you start a new browser session, or each time you log out. MFA does not cache (remember) your secondary authentication via Outlook on the Web. The only exception to this is via PC's in the University PC suites, where you will not need to use MFA.
  • When signing in via any other client / mail app / outlook app, you will need to reauthenticate at least every 60 days. To activate this option, remember to click 'Dont ask again for 60 days' when you are authenticating via secondary authentication. 
  • After initial set-up, MFA remembers your last used secondary authentication option. e.g. if you choose verification via push notification the first time you set up MFA, this will automatically prompt after you enter your password to sign into your email on a new browser session / other device. To switch secondary authentication preference, click 'Sign in Another Way' and chose one of the alternative methods available.
  • MFA is not enabled in any of the Campus PC Suites. You will simply need to know your Username and Password when accessing from Campus PC Suites.
  • Should you lose access to your secondary authentication method (i.e. a lost or stolen phone) you will be unable to access your mail account. You will need to contact the Library and IT ServiceDesk in such instances to have your MFA credentials reset.
