In my Log In post I was hoping that One day, smarter Log In pages would be able to Trust my location. A mere 2 days later, Google announces Smart Lock (as part of Google Play Services 6.5 and Lollipop).
The Verge provides a good translation of what this will mean to regular users.
In a nutshell, you can now define a location as safe, and then your Lollipop phone won’t ask you to unlock it when you’re nearby—it’ll just let you straight in.
