It is accessible through [FirebaseAuth.DefaultInstance](/docs/reference/unity/class/firebase/auth/firebase-auth#defaultinstance). \n\n```c#\nFirebase.Auth.FirebaseAuth auth = Firebase.Auth.FirebaseAuth.DefaultInstance;\n```\n\nAuthenticate with Firebase\n\n1. Follow instructions for [Sign in with Twitter](https://developer.twitter.com/en/docs/twitter-for-websites/log-in-with-twitter/guides/implementing-sign-in-with-twitter) to get an OAuth access token and an OAuth secret.\n2. After a user successfully signs in, exchange the access token for a Firebase credential, and authenticate with Firebase using the Firebase credential: \n\n ```c#\n Firebase.Auth.Credential credential =\n Firebase.Auth.TwitterAuthProvider.GetCredential(accessToken, secret);\n auth.SignInAndRetrieveDataWithCredentialAsync(credential).ContinueWith(task =\u003e {\n if (task.IsCanceled) {\n Debug.LogError(\"SignInAndRetrieveDataWithCredentialAsync was canceled.\");\n return;\n }\n if (task.IsFaulted) {\n Debug.LogError(\"SignInAndRetrieveDataWithCredentialAsync encountered an error: \" + task.Exception);\n return;\n }\n\n Firebase.Auth.AuthResult result = task.Result;\n Debug.LogFormat(\"User signed in successfully: {0} ({1})\",\n result.User.DisplayName, result.User.UserId);\n });\n ```\n\nNext Steps\n\nAfter a user signs in for the first time, a new user account is created and\nlinked to the credentials---that is, the user name and password, phone\nnumber, or auth provider information---the user signed in with. This new\naccount is stored as part of your Firebase project, and can be used to identify\na user across every app in your project, regardless of how the user signs in.\n\n- In your apps, you can get the user's basic profile information from the\n [`Firebase.Auth.FirebaseUser`](/docs/reference/unity/class/firebase/auth/firebase-user) object:\n\n ```c#\n Firebase.Auth.FirebaseUser user = auth.CurrentUser;\n if (user != null) {\n string name = user.DisplayName;\n string email = user.Email;\n System.Uri photo_url = user.PhotoUrl;\n // The user's Id, unique to the Firebase project.\n // Do NOT use this value to authenticate with your backend server, if you\n // have one; use User.TokenAsync() instead.\n string uid = user.UserId;\n }\n ```\n- In your Firebase Realtime Database and Cloud Storage\n [Security Rules](/docs/database/security/user-security), you can\n get the signed-in user's unique user ID from the `auth` variable,\n and use it to control what data a user can access.\n\nYou can allow users to sign in to your app using multiple authentication\nproviders by [linking auth provider credentials to an\nexisting user account.](/docs/auth/unity/account-linking)\n\nTo sign out a user, call [`SignOut()`](/docs/reference/unity/class/firebase/auth/firebase-auth#signout): \n\n```c#\nauth.SignOut();\n```"]]
