Teens’ aversion to Facebook  jeopardizes not only the company’s feed ad revenue, but its dominance as an identity provider. The Facebook Login platform keeps people tied to the social network in order to easily access other apps without a separate username and password. But for younger users who ditch or neglect Facebook in favor of Instagram,  the tech giant stands to lose one of its most powerful wedges into our lives. Meanwhile, Instagram loyalists are forced to juggle multiple sets of login credentials to manage their personal, Finsta and business accounts.
