Microsoft MFA FAQ

What is Multi-Factor Authentication?

Multi-factor authentication adds a second layer of security to your online accounts. Verifying your identity using a second factor (like your phone or another mobile device) prevents anyone but you from logging in, even if they know your password.

Why do we need it?

Passwords are increasingly easy to compromise. They can often be stolen, guessed, or hacked — you might not even know someone is accessing your account.

Two-factor authentication adds a second layer of security, keeping your account secure even if your password is compromised. With Microsoft MFA, you will be alerted right away (on your phone) if someone is trying to log in as you.

How do I set up Microsoft MFA on my device?

Is it safe to put the Microsoft Authenticator app on my personal mobile?

Microsoft Authenticator is very safe and is used worldwide. You very likely already have one or more Microsoft apps installed on your phone (Outlook, Word, Excel).


Why when connecting to Remote Desktop does it try to connect and then just sit there waiting?

This could be because the Remote Desktop login is waiting for you to approve to logon on your phone. If you do not see a notification on your phone, try opening the Microsoft Authenticator App and signing in again.

Why do I only sometimes get prompted for MFA?

This will depend on the service you are trying to connect to. Some services allow you to save credentials, some do not, and some are configured by management to force a login every time for security.

As a general rule, most web portals will prompt every time, as you can access the website from anywhere in the world, whereas desktop apps are only accessible on your computer so will allow you to save your login. There are MANY exceptions to this rule and will also depend on your organisation’s security settings.

Why doesn’t Microsoft MFA prompt me every time I open Outlook?

Outlook (and other Microsoft desktop apps) will only need to authenticate once and will not need to authenticate again until you change your password.
This is because your login details are saved in the app.

Why do I get prompted every time I connect to Remote Desktop or VPN

The corporate network needs to be a secure environment, for this reason, we need to make sure the person connecting remotely is you, and not just someone who has remote access to your home computer.
