Dell, Twitch, Best Buy, Ford Motor, Pottery Barn, Nike, Patagonia, and Match no longer allow users to sign in with Facebook.

People can still sign in with Google, Twitter, or LinkedIn.

Jen Felch, Dell's chief digital and chief information officer cited privacy concerns as the reason for the removal.

Until about a month ago, shoppers on Dell's website looking for a new laptop could log in using their Facebook credentials to avoid creating a new username and password. That option is now gone.

Dell isn't alone. Other big brands, including Best Buy, Ford Motor, Pottery Barn, Nike, Patagonia, Match and Amazon's video-streaming service Twitch have removed the ability to sign on with Facebook. It's a marked departure from just a few years ago, when the Facebook login was plastered all over the internet, often alongside buttons that let you sign in with Google, Twitter or LinkedIn.

Jen Felch, Dell's chief digital and chief information officer, said people stopped using social logins, for reasons that include concerns over security, privacy and data-sharing.
