When asked to fill in information on a website, most people will think twice. It's not a matter of putting their information out there, the majority of these people have some form of social media profile; it's a matter of taking the time to do so. There is now a way information can be linked from one site to another with the click of a link. What better way to share user information and save time than to have one database connected to the rest? Businesses have been utilizing this concept allowing a person to connect via their social media page and register quickly. The business has all the information when access is granted by the user and the user benefits from not having to spend time filling in registration forms. login-i.com
