Maybe ‘shareable identifier’ for npub.

And optionally if they want a Nostr Username, let them setup a NIP-05. It’s literally just a username in all aspects (I think) - login, sharing, search, comparing accounts if identical other info, auto-complete, etc. ability to setup a username later.

And then secret/recovery/master private key (or similar) for nsec. Ideally nsec backup is an in-app action after initial setup - “keep your account safe, sync to cloud, save to password manager, write down seed words”. Setup 100% complete.
