+## Spring Security OpenID
+
+This module contains articles about OpenID with Spring Security
+
+### Relevant articles
+
+- [Spring Security and OpenID Connect (Legacy)](https://www.baeldung.com/spring-security-openid-connect-legacy)
+
+### OpenID Connect with Spring Security
+
+### Run the Project
+
+```
+mvn spring-boot:run
+```
+
+### Obtain Google App - Client ID, Secret
+
+- We need to get client id and client secret by creating a new project at [Google Developer Console](https://console.developers.google.com/project/_/apiui/credential?pli=1)
+- We can follow these instructions to register our client application on their platform
+
+- Once we have the client id and secret, we have to make sure we add them to the application.properties file.
