No.
This question does not make sense. When creating a Xbox live account, you will need a email and password, the password will be saved onto your xbox so there is no need to input it every time you log on to Xbox.
I don't think you can.
they have to log in every time you want to play.
no
how long is an xbox live suspension When you go on your xbox and try to log into your account it should say how long the suspension is for. Also you can post on the Account Suspensions and Console Bans Fourm on Xbox.com to figure out how long and why you were suspended.
Log into your Xbox account through Xbox, then go to My profile, and find where it says Redeem Code, then you put in the code from the bottom of the card into the text box, it should automatically do everything else.
From my guess, they'd be on the system still. Clean out the system if you can.
Get the parental code or log on as the main user.
Well of course if you're speaking about xbox live. just sign out of the other persons account before you log in.
Better to just register online and make sure your account is active and ready, then log in on the xbox 360 itself. See if this works
