How to Reset MFA for a Microsoft Developer Program E5 Sandbox
Question details
The user is locked out of their Microsoft Developer E5 Sandbox because MFA codes are not reaching their Microsoft Authenticator app or alternate email.
- Product
- Microsoft 365 / Microsoft Developer Program
- Device & OS
- not provided
- Scenario
- Attempting to log into a Microsoft Developer Program E5 sandbox as an administrator.
- Observed behavior
- The administrator can enter their password successfully, but the login process is blocked because the required MFA codes fail to arrive at the configured Authenticator app or backup email address.
Gather your Microsoft Developer Program subscription details, Visual Studio ID, and sandbox tenant information, as you will need them to verify your identity and ownership.
Reset MFA via Another Administrator Account
Use this method if your E5 sandbox tenant has another active user with global administrative privileges who can reset your settings.
Microsoft Entra ID allows administrators to manage and reset authentication methods for other users within the same tenant. If you are not the sole administrator, this is the fastest way to regain access without contacting support.
Ask the other verified administrator to navigate to the Microsoft Entra admin center and sign in with their active administrator credentials.
In the left-hand navigation pane, go to 'Users' and then select 'All users'. Search for and click on your locked-out administrator account.
On the user's profile page, select 'Authentication methods' from the left-side menu.
Click the 'Require re-register MFA' button. This will invalidate the previous Authenticator setup and prompt you to configure MFA from scratch upon your next sign-in attempt.
Contact Official Microsoft Support
Follow this procedure if you are the only administrator on the tenant and cannot self-recover your MFA methods.

Frequently Asked Questions
Why did my Microsoft Authenticator stop receiving codes for my E5 Sandbox?
This commonly occurs if the Authenticator app loses synchronization, the account token expires, or the account was accidentally removed from the app. Network issues or battery optimization settings on your mobile device can also prevent push notifications from arriving.
Can I reset my own MFA if I am the only global administrator?
No. If you are the sole global administrator and lose access to your only MFA method, you cannot perform a self-reset. You must contact the official Microsoft Support channels to verify your identity and have their Data Protection team reset your authentication methods.
Should I create a new trial tenant to get access to Microsoft Support?
No, you should avoid creating an unrelated trial tenant just to access the support portal. Doing so complicates the recovery process. Proceed with a new trial tenant only if an official Microsoft Support representative specifically advises you to do so for ticket routing purposes.
