Facebook is testing different designs for the mobile login process for third-party apps and sites that connect with the social platform.
In December 2012, Facebook announced changes to the apps permissions process, which separates read and write permissions into different dialogs. This means users have the option to log into an application and receive a personalized experience using their name, friend list and other aspects of their profile, but they can reject the app’s request to publish activity on their behalf.
As that rolls out across desktop and mobile, the company has been testing different versions of the permissions dialog to improve the design and performance. The following is what users will see on an iOS device when logging into a site that uses Facebook Login. After users accept the first “read” permissions request, they can accept or skip the “write” request. They can also change their default privacy setting for the app. If an app wants to manage a user’s ads, events, notifications or other products, it will have to request this in a third dialog.
A similar version appears on Android devices, as Blink VP Planning and Media Eti Suruzon shares in the following screenshots.
Compare these to the mobile design included in the image below, which was part of Facebook’s original blog post about the change in December. As far as we’ve seen, the web and native iOS 6 implementations appear the same as below.
