When Authy Backups are enabled, any new Authy multi-device installations configured on your account should automatically sync your existing 2FA account tokens to the new device. This guide covers troubleshooting steps to take if you run into any issues with this sync.
Verify Authy Backups are Enabled
The first troubleshooting step is to verify that backups are enabled on your main Authy device. If backups aren't setup, your 2FA tokens won't be synchronized to the new device. For help with turning backups on, see Enable or Disable Backups and Sync in Authy.
Verify the Authy ID
If you're missing any synchronized 2FA account tokens, check the Authy ID on each installation to verify that it matches. Different Authy IDs would indicate multiple Authy accounts are configured on your devices.
If you do see multiple Authy IDs, find a device that shows your current phone number (on the same screen as the Authy ID). You'll want to make this your main Authy account going forward. To help make sense, we'll refer to this as your "main Authy account" for the rest of these troubleshooting steps:
- For each 2FA account missing on your main Authy account, login to the account’s corresponding website using the code on your other device, and then temporarily disable two factor authentication.
- On your main Authy install, remove all devices except for the one labeled as “This Device”.
- On your main Authy account, Re-add your 2FA accounts.
- Make sure that Multi-device is enabled, and then uninstall and re-install Authy on your original device.
