You can export the Private Key of your iCloud Key in order to guarantee manual access to your wallet without requiring Ledger as a 2FA Key.
How to export the Private Key of your Cloud Key:
Navigate to the “Security” tab and click the three-dot button to the right of your 2FA Key.
Select the “Back up key” button.
Click the “Reveal” button to view your Private Key which you can copy and store safely.
Note: Never share this key with anyone. If a person has your Device Key and Private Key of your Cloud Key, they can access and control your Fuse wallet.
In case your Private Key gets compromised, your Fuse wallet is still safe as long as you have access to your Device Key. However, change the Cloud Key as soon as you’re aware that it is compromised.
