+## OpenID Connect
+
+The idea of an _authorization_ open standard started with [OAuth](https://en.wikipedia.org/wiki/OAuth) around 2006. Because of a security issue, OAuth 2.0 superseded the initial version. OAuth 2.0 became an <abbr title="Internet Engineering Task Force">IETF</abbr> <abbr title="Request For Comments">RFC</abbr> in 2012:
+
+>The OAuth 2.0 authorization framework enables a third-party
+>application to obtain limited access to an HTTP service, either on
+>behalf of a resource owner by orchestrating an approval interaction
+>between the resource owner and the HTTP service, or by allowing the
+>third-party application to obtain access on its own behalf
+>
+>-- [RFC 7469 - The OAuth 2.0 Authorization Framework](https://www.rfc-editor.org/rfc/rfc6749)
+
+OAuth focuses mostly on _authorization_;
+the _authentication_ part is pretty light:
+it contains a section about Client Password authentication and one Other Authentication Methods.
+
+>The authorization server MAY support any suitable HTTP authentication
+>scheme matching its security requirements. When using other
+>authentication methods, the authorization server MUST define a
+>mapping between the client identifier (registration record) and
+>authentication scheme.
+>
+>-- [2.3.2. Other Authentication Methods](https://www.rfc-editor.org/rfc/rfc6749#section-2.3.2)
+
+OpenID Connect uses OAuth 2.0 and adds the _authentication_ part:
+
+>OpenID Connect 1.0 is a simple identity layer on top of the OAuth 2.0 protocol. It allows Clients to verify the identity of the End-User based on the authentication performed by an Authorization Server, as well as to obtain basic profile information about the End-User in an interoperable and REST-like manner.
+>
+>OpenID Connect allows clients of all types, including Web-based, mobile, and JavaScript clients, to request and receive information about authenticated sessions and end-users. The specification suite is extensible, allowing participants to use optional features such as encryption of identity data, discovery of OpenID Providers, and logout, when it makes sense for them.
+>
+>-- [What is OpenID Connect?](https://openid.net/connect/)
+
+Here are a couple of identity providers that are compatible with OpenID Connect:
+
+* GitHub
+* Google
+* Microsoft
+* Apple
+* Facebook
+* Twitter
+* Spotify
+
+In the following, we will start with Google and switch to Azure to validate our setup.
+
+## Setting up OpenID Connect with Apache APISIX
+
+Imagine we have a web app behind Apache APISIX that we want to secure with OpenID Connect. Here's the corresponding Docker Compose file:
+
+```yaml
+version: "3"
+
+services:
+ apisix:
+ image: apache/apisix:3.1.0-debian #1
+ ports:
+ - "9080:9080"
+ volumes:
+ - ./apisix/config.yml:/usr/local/apisix/conf/config.yaml:ro #2
+ - ./apisix/apisix.yml:/usr/local/apisix/conf/apisix.yaml:ro #3
+ env_file:
+ - .env
+ httpbin:
+ image: kennethreitz/httpbin #4
+```
+
+1. Apache APISIX API Gateway
+2. APISIX configuration - used to configure it statically in the following line
+3. Configure the single route
+4. Webapp to protect. Any will do
+
+Apache APISIX offers a plugin-based architecture. One such plugin is the [openid-connect](https://apisix.apache.org/docs/apisix/plugins/openid-connect/) plugin, which allows using OpenID Connect.
+
+Let's configure it:
+
+```yaml
+routes:
+ - uri: /* #1
+ upstream:
+ nodes:
+ "httpbin:80": 1 #1
+ plugins:
+ openid-connect:
+ client_id: ${{OIDC_CLIENTID}} #2
+ client_secret: ${{OIDC_SECRET}} #2
+ discovery: https://${{OIDC_ISSUER}}/.well-known/openid-configuration #2-3
+ redirect_uri: http://localhost:9080/callback #4
+ scope: openid #5
+ session:
+ secret: ${{SESSION_SECRET}} #6
+#END
+```
+
+1. Catch-all route to the underlying web app
+2. Plugin configuration parameters. Values depend on the exact provider (see below)
+3. OpenID Connect can use a Discovery endpoint to get all necessary OAuth endpoints. See [OpenID Connect Discovery 1.0 spec](https://openid.net/specs/openid-connect-discovery-1_0.html#ProviderConfig) for more information
+4. Where to redirect when the authentication is successful. It mustn't clash with any of the explicitly defined routes. The plugin creates a dedicated route there to work its magic.
+5. Default scope
+6. Key to encrypt session data. Put whatever you want.
Review Comment:
When the secret is too short, the following error log will appear. Do we need to specify here that the key length is at least 16?
```
err:failed to check the configuration of plugin openid-connect err: property "session" validation failed: property "secret" validation failed: string too short, expected at least 16, got 4
```
