Answer 1

Hi,  

Thank you for posting your question in the Microsoft Q&A forum, and I’m sorry to hear you're having trouble accessing your work account due to Microsoft Authenticator app. 

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? 
• Could you please confirm whether you are an IT administrator for your organization? 

Additionally, when your organization 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.  

  

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

Please note that forum advisors do not have access to user account settings and cannot assist with logging in, resetting passwords, or changing access rights.

I hope this information is useful. Additionally, as other users have raised similar concerns and may not be aware of where to share their feedback, I hope this response helps clarify the situation and suggests a potential next step. Highlighting this information can make it more visible to others in the community who may be facing the same issue, making it easier for them to find guidance and contribute their feedback as well. 

Thank you again for your time and for raising this important usability concern. If you have any further questions or need additional assistance, please don’t hesitate to reach out. 

I look forward to your thoughts on this.
