Opt for an authenticator app that offers a recovery feature. Certain 2FA authenticator apps allow you to save the websites you have added, making it possible for you to regain your authenticator access on a new device in case your phone is lost or the app is deleted. Each authenticator app has its unique way of handling backups. For instance, Duo Mobile, our recommended choice, stores its backups in iCloud or Google Drive, depending on the platform you use, and secures them with a special password for retrieval. On the other hand, Google Authenticator is linked to your Google Account and can synchronize accounts between devices.
