Federated Accounts

By default, the WaaS API only allows one account per email. If a user attempts to login using a different method but the same email as before, they will receive an EmailAlreadyInUse error.

For example: if the user created their account using Google Sign In and then attempts to sign in with Email + OTP using the same method, they will receive this error.

By default (if using the default LoginPanel), the SDK will automatically open the FederatedAuthPopupPanel prefab located at SequenceFrontend > Prefabs > FederatedAuthPopupPanel. This prefab can be customized to your linking or replaced in the LoginPanel prefab. This panel will explain to the user that duplicate login methods are not allowed and prompt them to return to the login screen and sign in with their associated login method (or a different email altogether).

Once the user has logged into their account; the SDK will automatically make a FederateAccount request (see SequenceLogin). This will associate the failed login method with that email as well so that the user may sign in with either in the future. Using our example above, the user would now be able to sign into their account using Google Sign In or Email + OTP.

Manually Federating Accounts

You may want to add a button to your app allowing the user to associate an additional login method with their email (especially if you are using Guest Login). You'll want get a reference to SequenceLogin and then call the appropriate FederateAccount method for the login method.

SequenceLogin login = SequenceLogin.GetInstance();
 
// PlayFab
login.FederateAccountPlayFab(titleId, sessionTicket, email, walletAddress);
 
// OIDC (Social)
login.FederateAccountSocial(idToken, loginMethod, walletAddress);
 
// Guest
login.FederateAccountGuest(walletAddress);
 
// Email
login.Login(email);
// Later ... Once you've received the OTP code from the user
login.FederateAccountEmail(email, code, walletAddress); 

where walletAddress is the address of the SequenceWallet you retrieved after authenticating the user.

Re-using the Default LoginPanel

To allow a user to federate/link their accounts manually using the default LoginPanel, simply call SetConnectedWalletAddress on your SequenceLogin instance or call SequenceLogin.GetInstanceToFederateAuth with the currently authenticated wallet address provided.

SequenceLogin login = SequenceLogin.GetInstance();
login.SetConnectedWalletAddress(authenticatedSequenceWalletAddress);
 
// or
 
SequenceLogin.GetInstanceToFederateAuth(authenticatedSequenceWalletAddress);

This will configure your SequenceLogin instance to federate the accounts instead of creating a new session.
