Changing the service tools device ID password on the PC and system
There is no advantage of changing the service tools device ID password unless the passwords on the PC and system are out of synchronization.
By default, the system manages the service tools device IDs and its password. As a result, you do not need to resynchronize the device ID passwords manually.
You can resynchronize the PC and service tools device ID password to make them both the same again. Since this password is actually changed at each successful connection, manually changing the password, except for synchronization, is not recommended.
