Issues with Microsoft Authenticator on a New Phone

Asked by CuriousPineapple42
I've recently switched to a new phone and I'm having trouble with Microsoft Authenticator. It isn't sending codes to the new device, but the problem doesn't seem to be with the phone number, as it's still tied to my old number, which I have already traded in. What can I do to resolve this issue? Should I get in touch with my company's IT support for help?

It sounds like you'll need to recover your account through the options provided by Authenticator. Keep in mind that transitioning to a new phone without transferring your Authenticator setup can lead to issues like this. It's a good reminder to check how to backup or transfer apps like this in the future.

ConcernedUser99: Yeah, definitely a tough lesson. Make sure to set up a backup method next time!
