Google has updated Google Play Services. Users will notice changes from these updates in their apps quickly. For most Android users, Play Services remains out of sight and under the hood, serving apps with application programming interfaces (API), OAuth 2.0 identity services, security, malware scanning, and other mobile services.

This is a big interaction fix for users who previously had to select from multiple accounts, create new profiles, and grant user permissions just to sign into an app. It wouldn’t be noticeable except for all the streamlined web sign-ins available, such as Google, Facebook, and Twitter, that reduce sign-in to a click. Now Android sign in to apps is reduced to a tap.
