This is unrelated to Halo 4, but I just don’t know of any other forums and it deals with Xbox Live.
I was playing today and I lost connection to Xbox Live and my profile was signed in elsewhere. I quickly signed back into Xbox Live without a problem and the proceeded to change my password. What I want to know is if this is a glitch or if someone actually was able to get into my account and if I’m still in danger. Thanks.
Any relatives you know that knows your account details/details is saved on their console and they might of signed into your account by accident, causing you to sign out.
If not then i suggest changing your password, which you already have done, but you can also contact microsoft support.
