Login with social Media i.e Fb, Linkedin, Google and twitter is my
favorite working area. I have integrated them in various websites.
How I will achieve this job:
the App with your site.
Do all App
How social media login or signup works:
Consider a user comes on your site and you provide the facility of login or
signup using any social media. When a user click on button he will be
redirected to that social media and user will be asked for login information to
enter. User will enter the information and the app will ask him permission. If
user permits it, then he is redirected to your site. Your website will fetch
all the information you needed.
