Snapchat is secretly planning the launch of its first full-fledged developer platform, currently called Snapkit. The platform’s prototypes indicate it will let other apps offer a ‘login with Snapchat’ options, use the Bitmoji avatars it acquired, and host a version of Snap’s full-featured camera software that can share back to Snapchat. Multiple sources confirm Snap Inc is currently in talks with several app developers to integrate Snapkit.

The platform could breathe new life into plateauing Snapchat by colonizing the mobile app ecosystem with its login buttons and content. Facebook used a similar strategy to become a ubiquitous utility with tentacles touching everyone’s business. But teens, long skeptical of Facebook and unsettled by the recent Cambridge Analytica scandal, could look to Snapchat for a privacy-safe way to log in to other apps without creating a new username and password.
