One of the core requirements of preparing an application for launch on the Google Apps Marketplace is integrating with OpenID-based Single Sign-On. This enables Google Apps users to access your application without creating and maintaining additional credentials. This lowers the barrier to entry for your application and creates a seamless on-boarding flow.
In addition to making your app easier to use, price OpenID can improve security for applications by reducing the number of places you need to enter a password. Of course, it’s also important to strengthen the security of the places you are entering your password, and yesterday’s launch of Two-step verification does just that.
Until yesterday, Google Apps customers using Google Apps’ built-in authentication mechanisms needed to provide a username and password (something they knew) to log in. Our launch of 2-factor authentication, which we’re calling Two-step verification, enables users of Premier, Education and Government Editions to additionally require having something in possession- a mobile phone- to log in.
So, if you’re a Marketplace developer and your customer asks you if your app supports 2-factor auth, you can answer an emphatic “yes” and send them over to the Marketplace to add your app to their domain.
