How to complete erase the email from Microsoft Authenticator App?

Question

I added my coworkers email into my Microsoft Authenticator app. Now, that she’s back to work I removed it from my Authenticator app, but each time she tries to sign in I get a notification “Approve Sign-In?” to enter the number. When I click on that notification it takes me to the app and says “Sign-In Error. Error finding an account to complete multi-factor authentication. You may need to add the account again.”

how to make my phone forget that email completely?! Please help!!

Hi @Anna Sokolov

Thank you for posting your question in the Microsoft Q&A forum.  

Following your recent inquiry regarding the continued sign-in notifications for your coworker’s Microsoft account, despite having removed the account from your Microsoft Authenticator app, we would like to provide some clarification and guidance. 

Although the account has been deleted from your Authenticator app, your device may still be registered as an approved authentication method for your coworker’s Microsoft account. As a result, sign-in requests are still being routed to your phone, which leads to the error message: 

**“Sign-In Error. Error finding an account to complete multi-factor authentication. You may need to add the account again.” **

To fully resolve this issue and ensure your device no longer receives these prompts, please follow the steps below:   

Action Required by Your Coworker: 

1. Sign in to https://mysignins.microsoft.com/security-info. 
2. Under Security info, locate any entries related to: 
   • Microsoft Authenticator – notification 
   • Authenticator app 
   • Choose device names that may correspond to your phone 
3. Select “Delete” next to those entries to remove your device from her account. 

If the sign-in prompt continues to appear on your phone after these changes, we recommend restarting your device. This helps ensure that any residual authentication requests are cleared and that the app resets its connection to previously linked accounts

If your coworker is part of an organization using Azure Active Directory, she may also need to contact her IT administrator to ensure the device is fully removed from her account profile. 

Please let us know if you need further assistance, we’ll be happy to help.
