I got a new phone and when transferring all my data over my linked accounts to the Authenticator app didn’t transfer over. Since now I can’t access the app I can’t get the codes, how can I get my accounts back onto my Authenticator app?

Microsoft Security Microsoft Authenticator

    So this goes to two options first of you have your old phone or have backed up this to your cloud and second if you don't have previous access

    If old phone is there then go to settings then backup and turn it ON. Then would be able to restore it from cloud (Can use Normal searches or AI for steps if needed).

    If you have no backup at all then can use recovery codes,SMS or Voice calls,Backup Email Address,Backup Keys, Admin Reset,Setting up whole app again

    Ask your tenant/global admin to:'Re-register multifactor authentication forthis user" in Azure AD -> Users -> Authentication methods.
