When I switch from my Azure primary directory to Azure AD B2C directory, I need to approve the switch in Authenticator. The account name in Authenticator is very special. The account name is admin_mydomain.com#EXT#@mydomain.onmicrosoft.com. My Azure primary directory login name is admin@mycomain.com.
I got a new phone last week. I have restored all account details to new phone and scanned all other accounts’ QR codes. But I don’t know where to fine the QR code for the special account of Azure AD B2C directory. I have never aware this issue before. I will not be able to login my AD B2C directory if I lost my phone. It is a common issue for everyone who has Azure AD B2C directory.
I set the account up first time with a pop up wizard from Azure.
Please help me with this issue. Thanks.
