A bit light on details
This article is a bit light on details - how does only ever signing in once improve security?
Ok, I get that if you don't have to sign in multiple times, things like keyloggers cant grab your password. However, if your phone is stolen then the thief immediately has access to everything in your phone because your automatically logged into all of your apps. And I cant imagine it would be that hard to come up with a new type of malware that gets into your accounts because once it is installed on your phone, all the other apps are already logged in.
So I'm really not getting the benefits here except maybe, maybe against keyloggers. Anyone able to provide more details?
