> How members work in a Geenius MVP web app: invitations, sign-in by e-mail code or link, sessions, approval, blocking, export and erasing.

Members are the app's own people, such as clients or customers. They are never Geenius OS accounts.

- **Sign-in** by e-mail code or magic link, with sessions per device, rate limits and lockout.
- **Invite** by e-mail, resend, or let people request to join and approve them.
- **Block** signs a member out everywhere; **sign out** does the same without blocking.
- **Export** gives everything kept about a member; **remove** erases them with their records.
- **Single-user** mode makes an app for one address.

Test-mode mails to test addresses stay in a dev outbox.
