How do I delete my account from a different Xbox or keep them from signing in ?

You would have to delete the account from that specific console. There's not a way to do it remotely.

If you are on an xbox one you would just need to go to account.live.com and change your password this will then require them to put the new password in when they try to sign in and if they dont know it then their not going to be able to sign in.

That is the only solution to stop them from signing in on your account on their xbox. like Smwutches said there is no way to actually delete the profile remotely.

How to proceed when xbox.com says the account doesn't exist. both my kids have accounts using xboxfamilylive.com email addresses from when we had a family account.

I haven't been able to sign them in on a computer for over a year even though the xbox itself has had no problem signing them in until today.

All this extra security garbage we keep having to go through is getting utterly ridiculous.

If I can't even get into the account how can I do even the basics or risk deleting the profile on the xbox?

So whenever I log onto Minecraft with my Microsoft account it logs me into Xbox/Microsoft related apps with that account, that’s just a bug? I hope they resolve it or change it in some way so I can login to a different account on Xbox then a different account on Minecraft without having to keep signing in and stuff. Also how do I reinstall the old Minecraft launcher or find it on my pc, I deleted it after installing the new one

From what i know, the only way to do that would be to change the gtag on the old one to something different then change your new account to that gtag, as there is no way to delete an account, they have to keep them active for like 6 years after creation.
