My Device is lost/broken, how can I recover my NGRAVE key/ are my assets safe?

Your assets are safe, don't worry. Even if somebody finds your ZERO, they can't access it without the PIN code an/or fingerprint(s).

To recover your assets, you can import your backup in another ZERO or any other wallet. If you want to import your Perfect Key backup in another wallet that uses mnemonic seeds, you can convert it to that format.
