Google has made a change to Chrome OS to move user login from the machine to browser. The feature was first mentioned on Oct 13: “Using Chrome as our login manager has a number of potential benefits. Explore these tradeoffs and decide what to do about login manager.” The code was checked in on Dec 14: “An early version of this change’s finally in. It’s not ready for daily use yet, and we haven’t gotten network picker on there or anything yet, but at least we’ve got a baseline in there. I’m filing issues for follow-on work.” There’re lots of potential benefits to having users log into machines via browser. In particular it makes syncing easier and furthers the notion that you can log into any Chrome OS machine and have exactly same experience as you would on any other machine. The fact that users can’t download any software to Chrome OS computers furthers this experience.
