The Surface UEFI password cannot be reset, and Microsoft cannot retrieve it.
For a Surface bought from an auction site, the supported options are:
- Check with the previous owner or the organization that managed the device to get the UEFI password.
- If the device was managed by an IT department or another owner, contact them for the password.
- If that is not possible, use Microsoft service and support options that may be available to assist:
- Send the device to Microsoft for service
- Use an in-person service center where available
- Review self-repair options if technically experienced
If the device is part of an enterprise, UEFI settings may be locked to enterprise specifications.
