switch device code help

i generated a code to switch device but then i decided to keep using the account in the same device. will my account got deleted in a week or is it only happen if you dont play the account for a week? im still actively play the said account now. im under the impression that the code have to be used otherwise the account will be deleted.

from what i have seen, you have to keep generating a new id and password before the week is up to keep that data, or otherwise it will be deleted. but if you switch devices and/or switch back and don't generate a code you should be good.
