Multi-Factor Authentication (MFA)
What is MFA?
Multi-factor Authentication (MFA) or Two-step verification is a security feature that TU Dublin has deployed to protect your account.
Two-step verification is more secure than just a password
- It relies on two forms of authentication: something you know, and something you have with you.
Why is it useful?
- Using two-step verification can help protect your account, as it prevents malicious hackers from signing in to your account if they know your password.
- TU Dublin highly recommends using the Microsoft Authenticator App
What forms of verification can i use to access my account?
The Microsoft Authenticator app helps you sign in to your accounts when you're using two-step verification. Two-step verification helps you to use your accounts more securely because passwords can be forgotten, stolen, or compromised.
Microsoft Authenticator will prompt you to enter a number displayed on the sign-in screen when approving an MFA request in Microsoft Authenticator. This further protects you from potential accidental approvals and phishing attempts.
When you use your TU Dublin email address and password to sign in to an application connected to Office 365 you will be prompted to enter a number in the authenticator app.
Enter the number shown on screen into the authenticator app screen like the one below
