Thank you, Al Hill for the information.
Dome95, at this point, as Al suggested, it is better to contact Medion for support, based on your product's manual (page 42), there isn't a way to delete the password:
Keep your password in a safe place. If you forget your
password, you have no way of deleting it. If this happens,
contact your service centre.
Hope this information helps.
