Facebook is dominating Google, Yahoo, & Amazon in this niche area
 

Think about the last time you signed up for a digital product or service. Did you make a new account or did you skip the hassle by registering with one of your existing online identities?

There's a good chance it was the latter: 88% of consumers have logged into a website or app using an existing social network account, according to customer identity management provider Gigya. That's up 11% from 2014.

Gigya studied the data from more than 700 of its customers, and discovered that more than 60% of people who used social logins sign up with their Facebook accounts.
