Facebook login has become crucial for all the sites. Keeping the user perspective in mind, it saves a lot of energy and time of the user to fill those lengthy forms for new account creation and just by login in using the Facebook account, a new user account can be created.
For the site manager it becomes very easy to fetch all the user data which is readily available on the user’s facebook account. So, this becomes a win-win situation for both the parties.
Now implementing this Facebook login for Android and iOS app is bit of a challenge for the developers. We were also facing the same issue. Thought of blogging about it to help my fellow developers overcome this challenge.
How do we do it?
- Go to https://developers.facebook.com/
- Login using the credentials
- Go to Manage Apps > Create New App
