Question: My old phone died and my Authenticator codes went with it. How do I get back in?
A
Answer: You can move Google Authenticator to a new phone without the old one, but only if your codes were saved somewhere other than that phone. Google Authenticator syncs codes to your Google Account when you sign in to the app, and Microsoft Authenticator and 1Password keep backups of their own. If the codes never left the old phone, you recover each account one at a time with a backup code, a recovery email or phone number, or the site's own reset form.
