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 sign in via One Tap, a simplified version of Sign in with Google.
The new SDK is called Identity Services, and it consists of several APIs for logging in to external websites. Identity Services includes Sign in with Google, the login button that allows users to log in to external sites such as Reddit with their Google account. 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 as a beta last year, but the feature is now becoming widely available. One Tap is similar to Sign in with Google, but is primarily intended for mobile sites and apps. It is a prompt that crosses 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 such as 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 new versions of Apple’s operating system.
