We're working on a remote backup service feature that will let you store service keys in a safe Authenticator Backup based on the cloud and retrieve them in the event that your phone is lost.
Your device can create secure 2FA (two-factor authentication) tokens for your internet accounts using the Authenticator app.
Installing the Authenticator app on your new device will grant you access to your Keys in the event that you lose or damage your phone.
The program creates Time-based One-time Passwords (TOTP), which are then kept locally on the user's phone without access to the internet.
The Authenticator app is a straightforward and free tool for Authenticator that creates time-based one-time passwords (TOTP).
