Account stolen and login info changed apart from username.

logging into third party Minecraft launchers is at the users discretion, some of them are not real and just harvest your email and password. i would take this as a warning about logging into third party programs that have no affiliation with Microsoft.

Hey there!

Nice to meet you! My name is Christian, an independent advisor. I'm here to help you out.

You may need to fill out the account recovery form:

If it doesn't work, you may have to contact Xbox support for advanced account recovery:

https://support.xbox.com/en-US/contact-us

Just a reminder that please avoid sharing personal information including your email address. In the community forums no one, including Microsoft support, can review account information.

I hope this helps.

Best Regards,

Christian.

Also if you have access to a computer I recommend removing all card info and changing all your credentials for login as well if it was stolen.

Sorry if it was.

Yeah, if something gets stolen, call the police. You'll also want to change the password(s) on your account(s) so they can't be accessed from the stolen Xbox. You may also wish to contact Support and report the stolen console/ accounts just in case credit
card info has been used, or something's been done on or to the account that would get it banned.

I have found a fix for this for my 2 kids switches. Apparently when you create an account with microsoft and use it to log into minecraft it creates an xbox account for you and assigns a auto generated username. All i had to do wasgo to xbox website on
my comp and login using the microsoft login info. Once it logged into the account i went under settings and changed the gamer tag.
