Problems logging into the Microsoft Authenticator app. The app will not allow me to verify myself within the app. The email address is ‘[Moderator note: Personally Identifiable Information removed]’. I need this email for my job, but I am unable to log into [Outlook.com] on my phone. This is because the Authenticator app is not working

Hi lukas,

I’m sorry to hear that you are having trouble signing in to your work email account on your phone.

To better assist you, could you please clarify the following:

Have you previously set up the Microsoft Authenticator app on any device for this account, or is this your first time trying to sign in?

If so, are you currently using the same device where you originally registered the Authenticator app? Have you recently switched to a new device?

Additionally, when your company enforces multi-factor authentication (MFA) and only allows verification through the Microsoft Authenticator app, the system will not display other options such as SMS, email, or phone call unless those methods have been configured by your administrator. That’s likely why you're being prompted exclusively for the Authenticator app.



If you haven’t installed the app yet, you can follow this official guide to get started: How to add your accounts to Microsoft Authenticator - Microsoft Support



You can also refer to this article for instructions on signing in using the app: Sign in using Microsoft Authenticator - Microsoft Support



If you need further assistance, you can reach out to your IT administrator and share the steps outlined in the article Manage user authentication methods for Microsoft Entra multifactor authentication . This will help them assist you in resetting your MFA settings and restoring access to your account.

In case you do not know who is your IT admin, kindly refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support





Once this is done, you’ll be prompted to set up MFA again on your new device during your next sign-in.
