How do I get access to my business email account when I am the only administrator and I cannot receive messages from the authenticator app? I upgraded my phone and did not back up the Authenticator app before deleting it from my previous phone.

Question

I transferred my information from my old iPhone to my new iPhone, and I am no longer able to sign into my business account with the two-step verification process. The authenticator app on my new device is not receiving the verification information. As the only administrator and user on my small business account, how do I access my email??

I did not back up the original authenticator app and no longer have access to it from my previous device.
