Dear Nostrich Hatchlings:
You know "Not your keys not your coins"?
this is "Not your npub/nsec, not your Nostr"
if you don't keep and manage your keys, um, buh bye.
Discussion
Some kind of a main profile with subprofiles would be good. Maybe store the keys for the main profile securely in a hardware wallet and only use the subprofiles daily with the keys on a mobile device.
Would be good to have best practices and useful tools for this document end and shared/available
Fantastic - great minds....
