I try to log in to a sharepoint of our partner company in which I've been registered since last year.
Upon log in, a verification code is sent to my old phone number which I'm no longer able to refer to. Even I choose "another option", possible options are all related to this old phone number.
I asked to the partner representative how to change the registered phone number, but they cannot solve it and propose me to reach to Microsoft team.
According to them, it seems that my account is accessing to another MFA than theirs. (I don't understand what it means.)
Could you kindly advise how I can log in to the site?
