[Conduct an impact assessment](/identity/sign-in/web/gsi-with-fedcm) to confirm that user sign-in continues to function as expected. \n|\n| Support for the Google Sign-In library is deprecated, see the [Deprecation and Sunset](/identity/sign-in/web/deprecation-and-sunset) guide for more.\n\nSupported environments\n----------------------\n\nGoogle Sign-In officially supports the following browsers and platforms:\n\n- Google Chrome on macOS, Windows, Linux, Android, iOS\n- Mozilla Firefox on macOS, Windows, Linux\n- Safari on macOS and iOS\n- Internet Explorer versions from 8 to 11 on Windows\n- Microsoft Edge on Windows\n\nKnown issues\n------------\n\nThe following are known issues that you might encounter when using Google\nSign-In.\n\n### Third-party cookies and data blocked\n\nWhen enabled, this privacy feature deactivates all cookies and storage within\nthe iframe. Google requires this for secure user authentication.\n\nOne solution is to ask users who have disabled third-party data to create an\nexception for `https://accounts.google.com` by adding `accounts.google.com` to\nthe allowed domains. In Chrome, do this in `chrome://settings/cookies`.\n\nIf many of your users enable this feature (some companies enforce this\nsetting for all their employees), another workaround is to implement a\n[server-side OAuth 2.0 flow](https://developers.google.com/identity/protocols/oauth2/web-server).\n\n### Chrome on iOS in Incognito Mode\n\nGoogle Sign-in does not support incognito mode on Chrome on iOS.\n\n### Safari with Intelligent Tracking Prevention\n\nThis new feature of macOS High Sierra and iOS 11 deactivates third-party cookies\nevery 24 hours, unless the user interacts with one of the page of the\nthird-party domain. The Google Sign-in library relies on cookies to securely\nauthenticate the user. It potentially detects that the user is logged out every\n24 hours. The user must go through the sign in flow again to reactivate the\ncookies.\n\nAny other issue?\n----------------\n\nGo to our\n[GitHub issue tracker](https://github.com/google/google-api-javascript-client/issues)\nfor any other issue with the Google Sign-In library."]]
