Google One Tap, integrated with Descope SDKs, offers a streamlined authentication method that enhances user sign-ups and retention by eliminating the need for new credentials and reducing cognitive load. This approach relies on the Federated Credential Management (FedCM) API, which enhances privacy by allowing the browser to manage identity confirmation without relying on traditional methods like cookies or redirects. Implementing One Tap can significantly boost user engagement, as demonstrated by success stories from companies like Reddit and Pinterest, which reported substantial increases in sign-ups and retention. Descope also allows for post-authentication user journeys, enabling actions like phone verification and progressive profiling, thereby providing a seamless and personalized user experience across both desktop and mobile platforms.
