Authenticator 모바일 (개인)계정복구 하는데, "휴대폰 로그인 설정"이 안됨.

Question

최근에 휴대전화를 바꿨고, 기존 핸드폰의 authenticator 앱에서 "클라우드 백업"을 켰고,

새로운 폰에 microsoft Authenticator 앱을 깔았고, "계정복구"를 눌러서 기존 계정을 가져왔는데,

"휴대폰 로그인 설정"을 하려고 하면 자꾸 에러가 뜹니다.

안옮겨집니다. 왜그렇습니까?

찾다찾다, tenant 'Microsoft Services' 까지 가봤는데, 제 계정이 없다고 합니다.

(아래와 같은 문제가 뜹니다.)

제 계정에 무슨 문제가 발생한겁니까???

Message: AADSTS50020: User account '******@gmail.com' from identity provider 'live.com' does not exist in tenant 'Microsoft Services' and cannot access the application '74658136-14ec-4630-ad9b-26e160ff0fc6'(ADIbizaUX) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account.

Hi there,

I’m Cherrelyn, and I'm here to help.

The error message you're seeing means your personal Microsoft account (like ******@gmail.com) is trying to access a resource that belongs to an Azure Active Directory (AAD) tenant, where it doesn't exist as a registered user. This happens when a personal account is used in place of a work/school account, or when an app is expecting an organizational login.

Please try these suggestion:

• Remove and re-add the account in the Authenticator app using your Microsoft personal login.
• Make sure you're not logged in with a work/school account elsewhere in the app or browser.
• When setting up mobile sign-in, choose your personal Microsoft account, not an AAD-based login.

I hope this will help and if you have any question please don't hesitate to reply to this thread.

Warm regards,

Cherrelyn
