Cannot active member on groups Azure

Question

I am trying to log in to Azure to activate member groups. After successfully passing the login screen, I was prompted to authenticate using two-factor authentication (2FA) via the mobile app. However, I have accidentally deleted the authentication app from my phone, and now I am unable to complete the 2FA process. What steps should I take to reinstall and reconfigure two-factor authentication on my device so that I can successfully authenticate and proceed with activating the member groups?

Hi @tuan.ito

Thank you for posting this in Microsoft Q&A.

I understand you are accidentally deleted the authentication app from your phone, and now you are unable to complete the 2FA process.

To reinstall and reconfigure two-factor authentication on your device, you will need to follow the steps below:

1.Contact your global administrator and ask them to re-register MFA for you it will be deleted existing authentication methods

2. Reinstall the Microsoft Authenticator app on your phone. You can download the app from the app store on your device.

3.Once you have reinstalled the app, you will need to configure it to work with your Azure account. To do this, you will need to open the app and follow the prompts to add your account.

4.Once you have configured the app to work with Azure AD Multi-Factor Authentication, you should be able to use it to complete the 2FA process and proceed with activating the member groups.

5.If you are the only global admin on the account and are blocked entirely, you can reach out to the Azure Data Protection team to restore access https://learn.microsoft.com/en-us/microsoft-365/admin/support-contact-info?view=o365-worldwide
