  title: Supabase Auth Admin Configuration API
  description: The Supabase Auth API (based on GoTrue) is a JWT-based API for managing users and issuing access tokens. It provides endpoints for user signup, signin with email/password, magic links, one-time passwords, OAuth social login, token refresh, user management, multi-factor authentication, and SAML-based single sign-on. When deployed on Supabase, the server requires an apikey header containing a valid Supabase-issued API key.
