I'm the co-founder and CEO of LaunchKey (https://launchkey.com). Through our mobile apps and API, we provide anonymous multi-factor user authentication without passwords for websites and native apps. I noticed your Authy tutorial on net tuts and was curious if you'd be interested in writing one for LaunchKey? Here's a quick overview of how LaunchKey works:

Instead of passwords, a user only enters their LaunchKey username and an authentication request is pushed to their unique device where they must authorize (or block) the request with a swipe of their finger. We also provide optional auth factors like geofencing (specify specific geographical zones your device must be physically located within in order to authenticate) and an in-app combo lock or PIN lock. All together, this gives you true multi-factor protection: possession + inherence + knowledge. And unlike two-factor authentication that works on login only, LaunchKey enables remote logout as well.

Let me know if you're interested. Obviously, we'd love to help out or assist in any way. We have plenty of documentation online at https://launchkey.com/docs

Thanks for your time!

Geoff Sanders
