If you have forgotten the password to the miner WebUI after changing it, you can reset the M2 Pro by following the steps shown in the image below:
Once reset is completed, you can use the default username (admin) and password (the serial number).
When prompted to update/change the password, please don't leave it blank, as this will cause an issue with login in the future. You may use the serial number again for the password instead of leaving it blank.
*Only perform this step when it is necessary.
