unless you backed up the account with the old phone (and the new phone is same O/S). You will need to have your email account reset (by the email admin). How reset works depends on your email provider. Often you just need a QR code from your email provider.
How am I supposed to set up the Authenticator app on my new phone without my old one?

I got a new phone and it will not allow me to set up the Authenticator for my personal email. Every time I request help I get no emails on my back up email. How am I supposed to set up the Authenticator app on my new phone without my old one? It’s a terrible endless cycle where nothing gets achieved. It even made me change my password for no reason and I am still unable to set up authentication.
