Supabase Auth API

The Supabase Auth API (based on GoTrue) is a JWT-based authentication service supporting user signup, email/password sign-in, magic links, one-time passwords (OTP), OAuth2 social login (Google, GitHub, etc.), token refresh, multi-factor authentication (TOTP/WebAuthn), SAML-based SSO, and administrative user management. Authentication uses an apikey header (anon or service_role key) plus JWT bearer tokens for user context. Per-project base URL: https://{project_ref}.supabase.co/auth/v1.
