Not sure if this is the right place to ask this question.
I have a web application using just html/js etc.. but would like to use graph api/rest api sharepoint data as the back-end.
Further I want to use following url credentials for Single Sign On in my web application.
I would like the web app to to be integrated with office 365 after login in to SharePoint online / portal.office.com
The question is what will be the process of authentication?
Do i need to look in into the adal.js?
Thanks in advance
