Linked to the credentials-that is, the user name and password, phone Next stepsĪfter a user signs in for the first time, a new user account is created and The former is needed to authenticate with the providerĪnd the latter to exchange the provider's credential for a custom token. If these providers are required to be used in unsupported environments, a Obtained for one project cannot be used with another. In conjunction with a specific client ID/secret, an authorization code As the authorization code can only be used The authorization code exchange using the OAuth client ID and secretĬonfigured in the Firebase Console. Instead, Firebase Auth offers the ability to handle the entire OAuth flow and One project (attacker) can be used to sign in to another project (victim). Websites to replay attacks where a Yahoo OAuth access token obtained for This is a critical security requirement and could expose applications and Providers such as Yahoo due to the inability of the FirebaseĪuth server to verify the audience of Yahoo OAuth access tokens. Unlike other OAuth providers supported by Firebase such as Google, Facebook,Īnd Twitter, where sign-in can directly be achieved with OAuth access tokenīased credentials, Firebase Auth does not support the same capability for user.LinkWithProviderAsync(provider).ContinueOnMainThread(task => )",Īdvanced: Handle the sign-in flow manually Providers to the same user allowing them to sign in with either. While the above examples focus on sign-in flows, you also have theĪbility to link a Yahoo provider to an existing user using To start the sign in flow, call SignInAndRetrieveDataWithCredentialAsync: Up a web view in which the user can enter their credentials. Other FirebaseAuth operations, this will take control of your UI by popping New () Īuthenticate with Firebase using the Auth provider object. Construct a FederatedOAuthProvider for use in Auth methods.į provider = Once your provider data has been configured, use it to create aįederatedOAuthProvider. This must be preconfigured in the app's API permissions. Otherwise,the flow will fail and an error would be shown to theĮnd user. Permissions, sdct-w has to be passed instead of the readonly OAuth scope For example if, read/writeĪccess is requested to user contacts and preconfigured in the app's API Preconfigured ones in the app's API permissions. Requested OAuth scopes must be exact matches to the Need to request permissions to Yahoo APIs under API Permissions in the If yourĪpplication requires access to private user data from Yahoo APIs, you'll Optional: Specify additional OAuth 2.0 scopes beyond profile andĮmail that you want to request from the authentication provider.
