Set up Auth0 by Okta as the identity provider for OIDC authentication

This document provides the steps to configure Auth0 by Okta as the identity provider (IdP) for OpenID Connect (OIDC) authentication.

Steps:

1. Create an Auth0 Account:

   • Go to Auth0 and create an account if you don’t already have one.

2. Create a New Application:

   • Navigate to the Applications tab.
   • Click Create Application.
   • Select Regular Web Application or Machine to Machine Applications based on your need.

3. Configure OIDC Settings:

   • Record the Client ID and Client Secret for future reference.
   • Configure allowed callback URLs for the platforms you want to authenticate (AWS, GCP, etc.).

4. Set Up Tenant Domain:

   • The domain for your Auth0 instance will look like: your-tenant-name.us.auth0.com.

5. OIDC Configuration:

   • Use the .well-known/openid-configuration URL for your Auth0 tenant.
   • Example: https://your-tenant-name.us.auth0.com/.well-known/openid-configuration.

6. Test OIDC Configuration:

   • Before integrating with cloud services, ensure that the OIDC configuration works by testing with tools like Postman.
