Within the Casa app, you have the ability to export the seed phrase for the mobile key. Exporting the seed phrase marks the key for replacement.
Exporting the seed phrase is designed to be used only in an emergency scenario in which Casa disappears unexpectedly or is otherwise unresponsive!
You can use the seed phrase you export to carry out Sovereign Recovery.
In the Casa app, you would:
- Tap the key icon beneath your vault
- Tap "Mobile Key"
- Tap "View Public Keys"
- Tap "BTC Account"
- Write down the Derivation Path, which should look like: m/49/0/1
- Go back 2 screens to the Mobile Key view
- Tap "Import or Export Backup"
- Tap "Export Private Key"
- Tap "Understood, Continue" if you are sure you do not need to use the key within the app anymore
- Write down the seed phrase
Now you can use that seed phrase wherever you need to recover your key!
