## What Supabase Auth is

Supabase Auth is a product for implementing authentication and authorisation in an app. It is built for apps that need access to Supabase Data APIs, Storage, Realtime or Functions.

It provides client SDKs and API endpoints to create and manage users. It supports passwords, magic links, one-time passwords, social login and single sign-on. Authentication uses JSON Web Tokens, while user and authentication data is stored in a project’s Postgres database. It can also trust JWTs from supported third-party authentication providers.

Pricing: Third-party authentication costs $0.00325 per Third-Party MAU above the subscription plan quota.
