This a post which contains the project with the multiple angular apps for the SSO i.e. Single Sign On. I have created the 3 very simple angular apps and configured angular-oauth2-oidc (https://www.npmjs.com/package/angular-oauth2-oidc)
Keycloak is an open-source IAM solution that helps its users secure applications without having to write complex code. This helps save time spent on development.
Here, I have added the screenshot of how to create realms and clients in keycloak. However I'm not going to explain about Angular installation and integration of it with oauth2-oidc package. You can easily get that from this link: https://www.npmjs.com/package/angular-oauth2-oidc.
Step 1: Download and Install Keycloak. Use this link to install and download: https://www.keycloak.org/docs/11.0/getting_started/
Step 2: Make sure that your keycloak server is running on port 8080
Step 3: Login in to keycloak with your username and password
Step 4: Go to Realm Setting and create Realm as given in the screenshot below:
Step 5: Once done with Step 4 go to Login tab and enable User Registration option
Step 6: Now go to clients menu from right sidebar and create the 3 clients as shown in below screenshots. Provide appropriate client id, valid redirect url and web origins shown in the screenshots:
Click on "Clients" menu from right sidebar to view all the created clients
Step 7: Install Node and Angular
Step 8: Clone the angular apps from below repositories:

https://github.com/jogkunal5/angular-sso-oauth2-oidc-keycloak-ssoapp1
https://github.com/jogkunal5/angular-sso-oauth2-oidc-keycloak-ssoapp2
Step 9: Once done with clone. Execute the npm install command for all apps and test the code
