Microsoft Authenticator

Question

Hello, I am currently experiencing issues with the Microsoft Authenticator app. When I try to log in to an application, it asks me to enter a security code generated by Microsoft Authenticator. Unfortunately, I have forgotten the security code, and I did not set up any backup methods. Is there any way to resolve this?

Hi Chuyên Minh

I assume that you don't have any other users created in your Entra ID/directory that has the global admin rights.

To resolve this issue,

We will try to reset the MFA setup of your account using PowerShell in admin mode.

Please follow the below steps for your account,

1. open powershell in admin mode
2. install the MSOnline module if u don't have already
3. 
4. import the msonline module and then connect to it
   5. connect to your admin account through the pop up appeared
   6. now run the command to reset the mfa setup for this account,
   below is the clear syntax, Set-MsolUser -UserPrincipalName "your-email@domain.com" -StrongAuthenticationMethods @()
5. After executing the above command, your mfa setup will reset.
6. now login into your account through browser by entering username and password.
7. a prompt will appear to set up mfa methods to secure your account.
8. at this point of time, set up your mfa using authenticator app in your phone as per the instructions provided.

P.S - I've done the above repro for myself, and it's working perfectly as expected.

Hi,

Thank you for the update.

Since you no longer have access to the device with the Authenticator app and do not have any backup codes/methods, here are the steps to regain access:

1. If this is a personal account:
   • Visit the Microsoft Account Recovery Page and fill out the form with as much detail as possible. Link -> https://support.microsoft.com/en-us/account-billing/help-with-the-microsoft-account-recovery-form-b19c02d1-a782-dee6-93c3-dc8113b20c42 Submit the request and then wait for verification.
   2.If this is a work/school account:
   • Contact your organization’s IT administrator. They can reset your MFA settings and provide you with new instructions for setting up the Microsoft Authenticator app.

Once your access is restored,

Configure backup methods like an alternate email or phone number.

Enable cloud backup in the Microsoft Authenticator app for future ease.
