allows visitors to use their Facebook profile to log into your website instead of creating a unique sign-in. Then, when a visitor uses Facebook to log in, they also grant you access to specific pieces of information.
That information may include their:
Email
Public profile
Likes and interests
Friends
Allowing users to log in with their Facebook accounts has several benefits for both you and the user.
Facebook login makes the process of logging in faster and much more convenient because visitors use an existing account and password instead of creating a new password. According to a survey by Digital Guardian, the average person uses their email address to create about 130 accounts. But most people don’t make that many unique passwords. Instead, over half of account creators reuse passwords for several accounts. This behavior creates serious security risks.
By using Facebook to log into accounts, visitors aren’t creating new accounts—and unknown security risks. Also, they have fewer passwords to remember, which makes logging in much faster and easier.
As the website administrator, you can view their Facebook data, which gives you valuable demographic information such as age, gender, education, address, and interests. Then you can personalize your website experience around that data so you can attract even more of your most important demographic.
