Description
I have moved all my Apps from my old Android phone to a new one. Unfortunately, all Apps worked properly except Keybase.
Keybase App is not logged in, and I don't have any other devices or paper keys. (Why doesn't Keybase tell users to backup their paper key like most Bitcoin wallets?)
I did a system reset on my old phone.
However,
- I have a full backup of all my Apps, including
/data/data - I have my Keybase passphrase
- I have access to the hardware of my old Android device
- I can remember the screen lock password of my old Android device
Is it possible to recover my Keybase private key cryptographically?
