Is there a way to add my xbox account to an xbox without any of the info

Hi,

the most important question: Did you use the search person option to check if the account still exists.

After some years of inactivity accounts will be deleted.

Hi there,

There is currently not a way to remove an account remotely. You can change the password on your account and the system will ask for it the next time it is logged in. Without the password the account cannot log in.

More info can be found
here.

When I try to re-add my account, it just prompts me to check my internet connection. Is there any way to add an account without internet? If not, I'm screwed lol

Your account gets accessed by someone who has access to your info. This is the only way that an account gets access without permission by the owner. Regardless the outcome, the only way for your account to warrent an Unauthorized Investigation is either
by unknowingly giving out your info or someone knows your email address then hacks into the account by trying to find the password (via hacking tools)

Hence why Xbox LIVE states not to give out your info to any one for any reason. Regardless.

This is absurd. I'm not going to have my wife re-purchase all of our games for herself. Microsoft needs to adapt. It doesn't make any sense that Microsoft adds new ways to use your Xbox account without a plan to handle increased usage.
