The Google Identity Platform is a system that allows you to sign in to applications and other services by using your Google account. Google Sign-In is one such method for providing your identity to the Google Identity Platform. Google Sign-In is available for Android applications and iOS applications, as well as for websites and other devices.
Users of Google Sign-In find that it integrates well with the Android platform, but iOS users (iPhone, iPad, etc.) do not have the same experience. The user experience when logging in to a Google account on an iOS application is not only more tedious than the Android experience, but it also conditions users to engage in behaviors that put their Google accounts at risk!
