Very well, the internal secret is oracle uses the great Single Sign-On (SSO) to simply achieve the amazing function.
As well known as the Single Sign-On (SSO) technology has been used on oracle (https://www.oracle.com/) over the past many years. Are you wondering the underlying principle? Fortunately #NikkiSiapno uses the concise and easy-understanding GIF image (https://lnkd.in/dmdtqTqU) to reveal this mysterious veil.
We supposed "Identity Provider" is oracle own's IAM mechanism located in its cloud, "Service Provider 1" is the 1st APP I mentioned "LiveSQL", "Service Provider 2" is the 2nd App I mentioned "Forums or AskTOM".
The last 3 Apps uses the same principle to achieve SSO function (only listed the first 2 Service Providers). Similarly we supposed "Service Privoder 3" is the 3rd App I mentioned "DevGym", "Service Privoder 4" is the 4th App I mentioned "LiveLabs", "Service Privoder 5" is the 5th App I mentioned "SQuizL".
