## What you need to know

What must be checked beyond local access when VMAccess resets a Windows VM password after Entra sign-in was installed?

## Potentially affected

Authorized recovery of supported Azure Windows VMs using VMAccess and Microsoft Entra sign-in, excluding domain controllers.

## DSE recommendation

Include restoration of the intended Entra sign-in path in the password-recovery plan.

## Article

## Source facts

Microsoft directs operators to rerun the Entra Login extension after using VMAccess to reset a VM password when that sign-in extension was already installed. VMAccess grants administrative privileges to the specified account and changes Remote Desktop settings during a user update. It is not supported on domain controllers. These recovery effects extend beyond changing the password alone. [Microsoft Learn](https://learn.microsoft.com/en-us/azure/virtual-machines/extensions/vmaccess-windows).

## Applicability

Use this review for an authorized Windows VM recovery where Entra sign-in is part of the intended access design. Confirm the VM role and original authentication arrangement before selecting VMAccess; do not treat this as a domain-controller recovery procedure.

## DSE recommendation

Include restoration of the intended Entra sign-in path in the password-recovery plan. Coordinate the local recovery step with the identity and workload owners. Record the required follow-up extension operation, the approved account, and the access paths to be tested. Keep any temporary recovery access under the same change record so it is reviewed after the intended sign-in path is restored.

## Verification

After following the supported procedure, check the recovery account’s access and privileges, then test Entra sign-in using an appropriately authorized identity. Inspect the extension execution result and reconcile any Remote Desktop setting changes with the approved design. Retain sanitized evidence for both access paths. Do not declare authentication recovery complete merely because the local password reset succeeded.
