That actually will likely be a short-term solution if companies are forced to unbundle.

Say Google is required to sell Chrome and/or Android. Problem is, billion people's Google accounts are signed into those devices. Solution is, you replace the "Google account" on an Android device with an "Android account" that uses Google auth for login. Then, if a user wants after that point, they can detach that, set different credentials, whatever.
