Snapchat announced a host of new features for its messaging app on Wednesday. The biggest change is the new "tap to view" feature that, as the name implies, allows users to simply tap the screen to play a video or story rather than continuously press and hold. Additionally, Snapchat now offers two-factor authentication, which you should enable right now. The app has also rejiggered the ways you can add friends. The new Add Nearby function will allow groups of people in close proximity to add one another to their friends list en masse while the addition of a selfie into the center of your snapcode lets people immediately know it's you.
