Hello,

I deleted my work account from an authenticator app of my old phone, to add it into my authenticator app of my new work phone, I did this because for some reason it was not letting me have the account it in both phone's authenticator apps at the same time. But now to add again my account to the authenticator app in my new phone it is asking me for a code from Authenticator app of my old phone but it is not there anymore, so I can't fill in any code. And I just have authentication options through the app, so I need the app. I also didn't enable the backup option. So now I can't add my account to the MS authenticator app, and I'm afraid that if I get disconnected from my email or something, I won't be able to log in, cause my account is not in any the authenticator app anymore. What can I do?

Thank you!

    Hello Garza Cuevas R. de la (Roberto),

    Thanks for your question.

    Losing the MFA app requires you having to contact the admins of the accounts in question for work or school accounts.

    You will need to contact the support teams of those applications to assist you in resetting your credentials or reach out to support https://support.microsoft.com/en-us/topic/customer-service-phone-numbers-c0389ade-5640-e588-8b0e-28de8afeb3f2
