A Facebook hack which left the accounts of more than 50 million users compromised may have also affected third-party apps such as Tinder, Spotify and Instagram, if people used their Facebook account to register for the services.

The added repercussions of the massive security breach were confirmed by the company later Friday, during a follow-up conference call with reporters. Facebook acknowledged that not only had hackers obtained the ability to access Facebook accounts of affected users, they could also access any other service in which a Facebook account was used for registration.
