nope, you can definitely DO that, I misunderstood what you were saying.
BUT know that just because you get a user name and log in, you still needed to have filed a TM30 within 24 hours of taking up residence at that address. SO you should file a TM30 in person (with your lease) and get the 800baht fine THEN apply to use the system and get the user name login with your landlords info
