hi guys, here is my situation.
I have added authenticator in my iPhone, but I erased all content and settings in my iPhone.
Then I found that I can not login my Microsoft 365 developer administrator account any more,
because of the MFA
any help will be appreciate.

    PS: I erased all content and settings in my iPhone because of my iPhone can not receive SMS,
    And after that action, it works.
