Auth0

As explained in Effective Platform Engineering

Auth0 is an identity platform that provides authentication, authorization, and identity integration services for applications and systems.

Auth0 is a SaaS identity provider for application authentication, authorization, and identity integration. It can provide a product-like access experience for platform infrastructure and custom APIs while using GitHub as the authoritative source for user and team information. section 7.3.1

A GitHub-backed flow authenticates the user, retrieves organization team membership, and returns a verifiable JWT whose claims can govern access to team resources. A platform CLI handles the device-oriented interaction, while Auth0 provides the OAuth2 flow and token issuance. section 7.3.1 section 7.3.2

Configure a CLI identity provider

Create an Auth0 tenant and native application for a platform CLI, configure a GitHub OAuth application, and automate the setup through the Auth0 Management API. The resulting CLI can authenticate users and obtain JWTs containing their GitHub teams. section 7.3.2

Figure 7.8 For Epetech, we would like our IDP service to have built-in or easily configurable means of integrating with GitHub, requiring authentication through whatever means we have set up in GitHub. As a result of (1) successful authentication, we want the IDP to (2) get the list of all teams the user is a member of in our GitHub organization. Finally, we want to (3) return to the user a secure means of accessing the platform infrastructure or custom API resources.

Trace the intended GitHub-to-Auth0 sequence: authenticate, retrieve organization teams, and return secure access to platform infrastructure or custom APIs. section 7.3.1

How Effective Platform Engineering covers it

How deep it goes

Explains GitHub authentication, OAuth2 exchanges, team-membership claims, JWTs, and automated tenant configuration.

Examples

Uses a GitHub-integrated platform CLI whose JWT contains organization team membership as an authorization claim.

What it assumes

Assumes GitHub organization administration and introduces access tokens, ID tokens, OAuth authorization, and device authentication.

What you can do after

Configure an Auth0 native application and automate it to issue verifiable JWTs for CLI-based platform access.

How it connects

Connects authentication, authorization, GitHub, OAuth 2.0, OpenID Connect, JSON Web Tokens, and identity-provider design.
