Imagine I have the following implementation:
firstApp.mycompany.com (angular 2 +)
secondApp.mycompany.com (angular 2 +)
myFourthApp.mycompany.com (react or anything else)
How can I have a single login that persists across all of my applications, so when user goes from one sub-domain to another to open a different application they won’t see the login again.
I searched Single-Sign-On but it seems like its an option when you want to use third party authentication providers which is not my case.
