If your app uses sync, single sign on is a must

With RAW photography on mobile now a reality, Adobe Lightroom for Android quickly exposes a major shortcoming of too many apps.

Adobe's done a lot of good things lately. Its Creative Cloud service makes the entire suite of Adobe applications more affordable (or at least the monthly cost is easier to swallow). Photoshop is as important as ever. Adobe Document Cloud finally brings that end of the business into the 21st century. And Lightroom is now growing on iOS and Android — recently adding DNG support on our fair platform.

Signing in to Lightroom, however, remains a less-secure throwback.
