Google releases One Tap api for single click mobile login

Google has released a new set of APIs for logging in via Google services. Developers can let users log in via One Tap, a simplified version of Sign in with Google.

The new sdk is called Identity Services, and consists of several APIs for logging into external websites. Identity Services includes Sign in with Google, the login button that allows users to sign in with their Google account on external sites like Reddit. The button does not change anything in terms of functionality, but the appearance does change. The button contains the name, email address and profile picture of the user.

New in the sdk is One Tap. The company announced that on last year as a beta, but the feature is now becoming widely available. One Tap is similar to Sign in with Google, but is primarily for mobile sites and apps. It is a prompt that scrolls across the screen so that users are not redirected to an external page. Both Sign in with Google and One Tap use tokens so that users can log in without having to enter their password first.

According to Google, One Tap already works with websites like Pinterest and Reddit. The feature is available on Chrome for Android, Windows, Linux and macOS. It doesn’t work on Safari in iOS. Google says that’s because of Apple’s Intelligent Tracking Prevention in the new versions of Apple’s operating system.
