itd be cool if #Amber had a version you could install on a phone, keep it offline, then use qr card scanning to authorize signing on another online amber using on your online phone with a nostr client ( perhaps you gotta re-up it every few weeks or something). the offline phone would effectively act as your hardware signer.
