To ensure the continued security and usability of your app, [migrate to\nCredential Manager](/identity/sign-in/credential-manager). Credential Manager supports passkey, password, and federated identity authentication (such as Sign-in with Google), stronger security, and a more consistent user experience. \n\nYou can provide seamless authentication flows to your users with Google's\none tap sign-in and sign-up APIs.\n\nWith One Tap sign-up, users are prompted to create an account with a dialog\nthat's inline with your app's content, so they're never taken out of context\nby a sign-up screen. With just one tap, they get a secure, token-based,\npasswordless account with your service, protected by their Google Account. And,\nof course, since there's such little sign-up friction, users are much more\nlikely to register.\n\nReturning users are signed in with one tap, even when they switch devices or\nplatforms. And for returning users, One Tap sign-in works with passwords, too.\nIf they've saved their password with Google using Android autofill, Smart Lock\nfor Passwords, or Chrome on any platform, they can share those credentials with\nyour app and get signed in with zero friction.\n\nReady to give it a try?\n\n[Get started](/identity/legacy/one-tap/legacy-get-started)"]]
