title: How to migrate Microsoft Authenticator App with Azure AD B2C account to new phone?
body: <p>With Multi-Factor Authentication enabled Azure portal, it requires users to approve every login in users’ Authenticator App.</p>
  <p>When I changed my phone, Authenticator app must be migrated to my new phone. I used Back and Recover function of Authenticator app. I backed up and recovered account details to new phone. As work or school accounts, the migration process requires Additional Security Verification, which requires to rescan all QR codes of all accounts in Authenticator app. I have rescanned all QR codes of work or school accounts that I created.</p>
  <p>Now my issue for this migration is Azure AD B2C account. It was created by Azure when I created Azure AD B2C directory. The name of the account in Authenticator app is <strong>admin_mydomain.com#EXT#@mydomain.onmicrosoft.com</strong>. It is not a work or school account. From the name, it may relate to my Azure login account (admin@mydomain.com a work or school account). I have spent many hours for it. But I still don’t know where this special account details stored. So I can’t get the QR code of the account for Authenticator app. I can’t finish my Authenticator app migration.</p>
  <p>This account authentication is required when I switch from Azure primary directory to Azure AD B2C directory in Azure portal.</p>
  <p>Please help me with this issue. Thanks.</p>
