OpenID Connect Setup Guide for Marketplaces

OpenID Connect (OIDC) is an authentication protocol that helps verify user identities and get profile information. Here's what you need to know to set it up for your marketplace:

• OIDC builds on OAuth 2.0, adding user authentication and Single Sign-On
• It improves security, is easy to set up, and enables Single Sign-On
• You'll need knowledge of OAuth 2.0, JWTs, SSL/TLS, and HTTP requests
• Common providers include Okta, Auth0, Google, and Omnidefend

Key steps to set up OIDC:

1. Choose an identity provider and register your app
2. Add OIDC to your marketplace backend and frontend
3. Set up user sessions and handle login/logout
4. Customize scopes to get needed user information
5. Implement security best practices like protecting secrets
6. Test and troubleshoot common issues

Remember to balance security and usability, handle mobile authentication carefully, and keep your implementation up-to-date.

Required Technical Skills

To set up OpenID Connect, you should know about:

• OAuth 2.0
• JSON Web Tokens (JWT)
• SSL/TLS certificates
• HTTP requests, responses, and headers

If you're not familiar with these, take some time to learn about them first.

Tools and Resources You'll Need

Here's what you need to set up OpenID Connect:

Common OpenID Connect Providers

Here are some popular OpenID Connect providers:

Look into each provider to see which one works best for your marketplace.

OpenID Connect Flows Explained

OpenID Connect (OIDC) has three main ways to check who users are: Authorization Code Flow, Implicit Flow, and Hybrid Flow. Each one works best for different situations. Let's look at how they work and when to use them.

Authorization Code Flow

This is the safest way to use OIDC. It's good for apps that can keep secrets safe, like web and mobile apps.

Implicit Flow

This way is less safe and not the best choice for new apps. It's for apps that can't keep secrets, like those that run in web browsers.

Note: Be careful with this flow. It's not as safe as others.

Hybrid Flow

This flow mixes the first two. It's good when you need both types of tokens that OIDC can give.

Choosing the Right Flow for Your Marketplace

Pick your flow based on what your marketplace needs:

Setting Up OpenID Connect: Step-by-Step

This guide will help you set up OpenID Connect for your digital marketplace. We'll cover three main areas: setting up the identity provider, adding OpenID Connect to your marketplace, and handling user sessions.

Setting Up the Identity Provider

To set up the identity provider:

1. Register your app on the provider's website
2. Get your client ID and secret
3. Set up redirect URIs

Adding OpenID Connect to Your Marketplace

To add OpenID Connect:

1. Set up your backend
2. Update your frontend

Handling User Sessions

To handle user sessions:

1. Create and store sessions
2. Save user info
3. Add logout feature
4. Manage session timeouts

Tailoring OpenID Connect to Your Marketplace

This section covers how to customize OpenID Connect for your digital marketplace. We'll look at getting more user info, making login better, and adding extra security.

Getting More User Information

You can ask for more user details when setting up OpenID Connect. This is done by using scopes in your authorization request. Scopes let you ask for specific user info.

Here are some common scopes:

To get this info:

1. Add the scopes you want to your authorization request
2. The user agrees to share this info
3. You get the info in an ID Token or from the /userinfo endpoint

Making Login Better

A good login experience helps users trust your marketplace. OpenID Connect has ways to make login fit your brand.

You can improve login by:

For example, you could use display=popup to show login in a small window.

Adding Extra Security

Multi-factor authentication (MFA) makes your marketplace safer. It asks users for more than just a password to log in.

To add MFA:

1. Set up your identity provider to use MFA
2. Choose what extra steps users need to take

Here are some common MFA methods:

Keeping Your Setup Secure

This section covers key steps to keep your OpenID Connect setup safe. We'll look at how to protect client secrets, check ID tokens, and stop CSRF attacks.

Safeguarding Client Secrets

Client secrets are key to keeping your OpenID Connect setup safe. Here's how to protect them:

Checking ID Tokens

ID tokens prove who users are. To make sure they're real:

1. Check the token's signature with the provider's public key
2. Make sure the token hasn't expired
3. Check that the token is meant for your app

Preventing CSRF Attacks

CSRF attacks can harm your OpenID Connect setup. Here's how to stop them:

Fixing Common Problems

Here's how to solve frequent issues when setting up and using OpenID Connect.

Dealing with Authentication Errors

When you face authentication errors:

1. Check the error message
2. Set log level to debug
3. Look at the OpenID Connect troubleshooting guide

Example of an error message:

idsvr-local-curity-idsvr-1  | se.curity.identityserver.sdk.errors.ExternalServiceException: Facebook user-info endpoint returned error: 400
