New xbox and having problems

[molten osprey]

i went out yesterday and bought my first xbox. got home and set it up, bought some stuff and played all day. it was fine and fun. this morning i got up to see it was off and when i turned it on i wont let me sign in. it says "because we are accessing sensitive info, you need to verify you password for (email)." i put my password in and it doesn't work. i also don't have access to my email anymore. and every time i out my password in it goes to the home screen and logs out. i have been looking at things to fix it but nothing has worked. it says i sent 2 friend request but i cancelled them because i didn't send them and i didn't know the people. i really want to get this fixed so i can play these games. i don't know if i got hacked or what. i am still logged in the microsoft browser on my phone and xbox app. but i cant change or add any info on the website. i need someone to help me quickly. i cant play my games either because I'm not on the owner account thank you in advance and please help me.

i have tried to fix my series x since 10 this morning. i have unplugged it, hard reset, reset, unplugged again and again, and tried to change my account info. i searched for the error code (error 400) and tried to look up many many videos about it. seems that only 1 other person has had this problem and didnt list how they fixed it. i have tried to fix it for so long, i have done so many things. yet nothing will fix it

Can you sign into xbox.com with the same account?

[molten osprey]

yes

but the things like microsoft.com to sign in dont let me and give me an error code

So you probably want to contact support since you have a old email linked.

[molten osprey]

okay

[molten osprey]

so the password was changed i guess

dont know to what but

and i dont have a phone number linked so there is no way to change anything

and i cant change anything without sending a verification code to the email, which i dont have access to.

thats why I advised to contact support
