#[0] thanks for a nice presentation at nostrica! There was some discussion on having a nostr keys as sign-up in other services.

I was impressed by how vida.page manages it. You can set up a profile there by using only the nostr profile, no e-mail/phone etc. required.

They don't ask for nsec key in sign-up/sign-in but only npub and a relay. They then send a verification key as nostr private message. Kind of the same way an email sign-up works.

Of course you still have to have a good nseckey handling when using the nostr client, but there is no need to trust the nsec-keys to any app/service that does not need it to sign stuff.
