Microsoft authenticator app not sending code

Question

I am trying to login to Azure Devops, however when I do I get prompt to input a code into my Microsoft Authenticator App. When I go on the app though nothing comes up to input the code. There are also no other ways to sign in except using the app, the only options I have are sign in are by putting in a code to the app or receiving a code from the app, which I am not getting either. I recently got a new iphone 15 and the app is fully up to date.

Thank you for posting this in Microsoft Q&A.

By looking at the description it looks like your account is not registered properly for authenticator app in your new Iphone.

In this situation you have only couple of options.

If you have multiple admin in your tenant then you can try to follow below steps,

You can re-register for MFA.

To perform this there is no option where you can reset your MFA by your own. You will have to contact Azure AD administrator in your organization to get MFA reset for your account.

If you don’t know who are the admins then you can follow below steps to know who are the admin in your tenant. There is a PowerShell way to find global admin in your Azure AD. However, to use PowerShell as well you will have to authenticate yourself first. For authentication again it will prompt for MFA to be completed.

I would suggest you ask one of your colleague to perform below steps and share the global admin details with you so that you can contact admin and get your MFA registerd.

• Open Windows PowerShell as administrator.

• Run command “Install-Module azuread”

• Once installed you can run command “Connect-AzureAD” and enter user credentials once it asks for.

• Once you login, you can run command “Get-AzureADDirectoryRole”.

• From the output you can copy the object ID of Global administrator

• Run command “Get-AzureADDirectoryRoleMember -ObjectId "Paste the object ID of global admin that was copied earlier"

• You will get the list of users with global admin role assigned.

 

Now you can contact any global admin from the list and ask him to perform below steps to reset your MFA so that you can re-register for authenticator app.

• Admin has to login to Azure portal and access Azure active directory.

• Once done they have to go to users blade on the left.

• Click on Authentication methods and click on “Require re-register multifactor authentication”.

• Now when you try to login to Azure services it will prompt you to register for MFA again.

If you are the only global admin on the account and are blocked entirely, then only option is you can reach out to our support team. You can look into below article to get support numbers depending on your country.

or creating a ticket through a different account:  https://learn.microsoft.com/en-us/microsoft-365/admin/get-help-support?view=o365-worldwide#phone-support

Create a ticket with Microsoft support team. Give them the tenant ID which is locked out in your description. Tell them that no admin account has access anymore and your partners also have no access anymore.

Once you create a ticket with support team you will have to work with our data protection team. You will have to first prove your identity against your tenant for security purpose. Post that this team will help you with help you in getting access to your tenant or unlock your account depending on your scenario.

Also, for the future, you can create an emergency access account (break glass) in Azure AD. This account will help prevent being accidentally locked out of your Azure Active Directory (Azure AD) organization because you can't sign in for any reason.
