Today email auth is working end-to-end.
Resend is delivering Supabase Auth mail, so new users can sign up with email and password, get a confirmation link, and finish account creation. Sign-in works the same way. Password reset now routes through /auth/callback with the PKCE exchange fixed, and confirmed emails sync into profiles.email_verified.
I marked DMC-101 (email verification on sign-up via Resend) done on the roadmap.
