Cant sign in to Xbox account?

So, I can sign in to my Microsoft account normally, see all my settings. BUT when I try to sign into Xbox with the password I know is right because I just reset it, it says incorrect password. It also replaces the email where it says 'Email code to _____' at the bottom from my gmail account to gu*****@rambler.ru. how can I fix this?

(Microsoft wont let upload pictures so just imagine it)
