Answer 1

Hi @Adriana Zuniga,

Welcome to the Microsoft Q&A forum.

Thank you for contacting us regarding the question on logging in with the 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?
• What issue you’re experiencing with the Authenticator app? Are you getting an error message, not receiving a code, or unable to approve the sign‑in?

Once I have a clearer understanding of the situation, I will be able to provide more targeted and effective assistance. Please feel free to share any additional details that may be relevant to this matter.

In the meantime, here are suggestions you can try:

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.

While we do not have access to internal systems or administrative tools required to resolve account-specific or backend-related, but we’ll continue doing our best to support you within the scope of our responsibilities.   

If you have any updates, feel free to leave a comment under this post. I’ll be happy to assist further.

Answer 2

To log into accounts using the Microsoft Authenticator app, follow these steps:

1. Open the Authenticator App: Ensure you have the app installed on your mobile device (available for both Android and iOS).
2. Select Your Account: If you have multiple accounts set up in the Authenticator app, select the account you wish to log into.
3. Initiate Sign-In: When prompted to sign in, you may see options like "Approve a request on my Authenticator app" or a number that you need to enter in the app.
4. Authenticate: If you see a sign-in request, open the Authenticator app and approve the request. You may need to enter your PIN or use biometric authentication (like fingerprint or face recognition) to complete the sign-in process.
5. Using Passkeys: If your organization supports it, you can also sign in using passkeys. Follow the prompts in the app to authenticate using your device's biometric features or PIN.

If you encounter issues, ensure that your device is registered with the tenant and that you have enabled the necessary authentication methods in your account settings.
