Backup encryption key is an alternative method to the encryption password for decrypting your Sync data. Like with the encryption password, your backup encryption key is never sent to us or any other third party, which ensures that we cannot decrypt your data. For it to be useful, you need to save the key in a safe location, while you can access your Sync settings with the encryption password.

Save the backup encryption key

1. Log in to your Vivaldi account in Settings > Sync.
2. Enter the encryption password.
3. Below your account info, look for Save Backup Encryption Key. On Android, look for Backup Encryption Key near the bottom of the Settings page.
4. Click on it and save the key file to your device.

The key is valid until you reset the remote Sync data. We recommend storing the key file in a location that can survive something irreparable to your device, such as an external memory drive or a trusted cloud service.
