Someone is changing the password of my account

How to access a compromised Microsoft account

Hello amber, I am sorry to hear you are going through this situation, then I recommend a link where you will find a guide on how to recover access to your account

You can also contact official support to try and get your account back.

Unless you had someone login to your account then changing your email password would be the only thing you need to do. Did they access your XBOX account? Also would be a very good idea to change your XBOX live password and add the security proofs to your
account. I have mine set to text me a code in the event someone would ever request a password change to my xbox account.

Hello Carolyn,

If you think someone has your account information. We recommend to
change your password. You can also remove the devices after you change your password. If someone does know the information, they will not be able to sign in again. Do you have any children? They could of signed in at a friends house and forgot to remove
the account.

Thanks,

Brad
