Authentication

Datafuse Auth makes it easy to implement authentication and authorization in your app. We provide client SDKs and API endpoints to help you create and manage users.

Your users can use many popular Auth methods, including password, magic link, one-time password (OTP), social login, and single sign-on (SSO).

About authentication and authorization

Authentication and authorization are the core responsibilities of any Auth system.

• Authentication means checking that a user is who they say they are.
• Authorization means checking what resources a user is allowed to access.

Datafuse Auth uses JSON Web Tokens (JWTs) for authentication. Auth integrates with Datafuse's database features, making it easy to use Row Level Security (RLS) for authorization.

The Datafuse ecosystem

You can use Datafuse Auth as a standalone product, but it's also built to integrate with the Datafuse ecosystem.

Auth uses your project's Postgres database under the hood, storing user data and other Auth information in a special schema. You can connect this data to your own tables using triggers and foreign key references.

Auth also enables access control to your database's automatically generated REST API. When using Datafuse SDKs, your data requests are automatically sent with the user's Auth Token. The Auth Token scopes database access on a row-by-row level when used along with RLS policies.

Providers

Datafuse Auth works with many popular Auth methods, including Social and Phone Auth using third-party providers. See the following sections for a list of supported third-party providers.
