I have a PHP-based web app that currently uses Google Sign-in with backend auth (see this link for exactly how I have it working now) to register and login users to my site.
I would like to add Microsoft Sign-in with the same control flow if possible, but I can't find an explanation of whether or not this is possible and how to accomplish this. Currently, all I need is the basic profile information. I'm not looking to do anything complicated.
So is this possible and if so, how exactly do I set this all up?
