You shall not pass (this time): Google+ tweaks permissions

Google's social network-powered sign-in system gives developers more nuanced options when asking for user permissions.

Google+ Sign-In is the social network's authentication service, used by a range of apps and services to simplify logging in for users. On Wednesday, Google announced that developers who implement it will no longer have to ask their users for all or nothing when it comes to permissions.

The update introduces incremental authorization so that an app's users don't have to be asked to surrender all app permissions at once. This could help educate people as to what an app or service is doing with those permissions, although it's not as far a step as giving users a line-item approval.

Google also said in its blog post that by encouraging developers to create a more granular approach to permissions, they will get their users to be more involved with the app.

An example the company gave was of an app that lets its users save a music playlist to Google Drive. The app would ask only for basic profile information on first login, and then only ask for Google Drive permissions when the user is ready to save a mix.

In addition, Google+ Sign-In now supports all Google account types, including Google Apps and Google account holders who don't have a Google+ profile.

To make it easier for developers to switch to Google+ Sign-In, and to encourage them to use the login service over other popular options like Facebook, Google is also offering Google+ Sign-In migration instructions.
