'Login with Snapchat' takes cold war with Facebook to next level

Features for synching with other apps is most aggressive move yet to capitalise on Facebook's problems

Snapchat users will be able to use their account on the messaging service to log in to other apps, export their bitmoji and post information from elsewhere direct in the Snapchat app, as the company makes its most aggressive attempt yet to capitalise on Facebook's woes.

The new features, collectively called "Snap Kit", offer a set of tools that developers can incorporate into their own apps. The Creative Kit feature is about getting content into Snapchat: similar to an earlier integration with Uber, it lets apps create personalised filters, stickers and lenses that users can share on Snapchat. Food delivery service Postmates, for instance, will let users throw an ETA for their food onto a picture - to let their friends know to hurry up.
