2010 - OneLogin - Single sign-on for SaaS apps to catch up with Symplified

Thanks to SaaS technology, a large number of business applications have appeared. Now companies can use multiple applications from different vendors (not just from Microsoft). But along with the wide variety of applications the problems of their integration and a single sign-on have come. Various platforms, marketplaces and SaaS associations are intended to solve these problems:, Intuit Partner Program, Google Apps Marketplace. OneLogin also tries to solve the single sign-on problem in simple and ingenious way. It is the centrally-administered username / password database + browser plugin, which makes working with a large number of SaaS applications very convenient.

It works like this. The user presses the button on the browser toolbar, and the page with list of all used applications is opened. Then he clicks on the needed application and logs in without entering login / password.

IT administrators can control all authentication data and sync it with Active Directory (or other directory via LDAP). It's also possible to limit allowed IP-addresses that can access apps. Of course, the level of security is dramatically increased.

In addition, OneLogin - is not just form-filler. It supports different authentication technologies, including OpenID, SAML, 2-factor authentication. But you can't use it with any application application - only with those that OpenLogin has official  integration. Although this list - is pretty long.
