The reach of Facebook and Google in the online world stretches way beyond the companies’ own websites.
Together, both companies account for 80 percent of so-called social logins, which enable users to sign in to a third party website using an existing social media or email account.
If you are a regular internet user, chances are you’ve come across the option to sign in at a website using one of the many social media or email accounts most of us have amassed over time. Many internet users loathe the time it requires to fill out long registration forms from scratch, in which cases the ability to use an existing login comes as a welcome facilitation. Potential privacy concerns notwithstanding, the adoption of social login services is rising: according to Janrain, a provider of social login solutions, 90% of online consumers have encountered social login before and more than half have those are actively using it.
To the companies providing the identities for social logins, these services constitute an additional source of potentially valuable information. It comes as no surprise that Facebook is the most popular choice for social logins, given the service’s huge user base. According to Janrain, the social network powered 46 percent of social logins in the third quarter of 2014.
