SpacetimeAuth - Overview

Note

⚠️ SpacetimeAuth is currently in beta, some features may not be available yet or may change in the future. You might encounter bugs or issues while using the service. Please report any problems you encounter to help us improve SpacetimeAuth.

SpacetimeAuth is a service for managing authentication for your SpacetimeDB applications. This allows you to authenticate users without needing an external authentication service or even a hosting server. SpacetimeAuth is an OpenID Connect (OIDC) provider, which means it can be used with any OIDC-compatible client library.

At the end of the authentication flow, your application receives an ID token containing identity claims (such as email, username, and roles). This token can then be used with any SpacetimeDB SDK to authenticate and authorize users.

Projects

SpacetimeAuth uses the concept of "projects" to manage authentication for different applications.

• Each project has its own set of users, roles, and authentication methods.
• Each project has its own configuration for email templates, web pages, and other settings.
• Each project is independent of a SpacetimeDB database and can be used by one or many databases.

Here are some examples of how you might use projects:

• You have a web application and a mobile application that both use the same SpacetimeDB database. You can create a single SpacetimeAuth project for both applications, therefore sharing a single user base.
• You have multiple SpacetimeDB databases for different environments (e.g. dev, staging, production). You can create a separate SpacetimeAuth project for each environment, therefore separating your users between environments.
• You have multiple SpacetimeDB databases for different applications. You can create a separate SpacetimeAuth project for each application, therefore separating your users between applications.

Users

Users are the individuals who will be authenticating to your application via SpacetimeAuth. Each user has a unique identifier (user ID) and can have one or more roles assigned to them.

Clients

Note

⚠️ Clients must not be confused with Users.

Clients (from OpenID Connect) are the applications that will be using SpacetimeAuth for authentication. Each client is associated with a single project and has its own client ID and client secret.

Roles

Roles are used to manage access control within your application. Each role is represented by a string (e.g. "admin", "user") that can be assigned to one or more users. Roles are included as claims in the ID token that is issued to the user upon authentication.

Inside your reducers, you can check the user's roles to determine what actions they are allowed to perform.
