If you're using a third-party authentication system, retrieve the appropriate token from that service (via API calls or SDK functions), then call the appropriate PlayFab API to link the player's account from that service to their PlayFab account: LinkFacebookAccount, LinkGameCenterAccount, LinkGoogleAccount, LinkKongregate, LinkSteamAccount, LinkTwitch, LinkWindowsHello. After a tutorial phase, gently encourage players to link your preferred choice of recoverable credentials to their account. Use an anonymous login to create new players with zero friction. Please be sure to check the Add-on Marketplace page for the service in question as part of setting up your title. Some services require that PlayFab have some additional information, such as an Application ID, in order to make the authentication call to that service for your game. This allows PlayFab to safely link to that account without being aware of the user's credentials in that service.Once you have logged in, those services will provide some kind of token, which can be passed to PlayFab.First, prompt the user to log into that service (more details in Login basics and Best Practices).Linking that account to PlayFab generally follows the same pattern: The third-party recoverable login mechanisms each involve prompting the user to log in via an appropriate SDK or third-party API call. If a player enters a bogus email address, you can still use the PlayFab Game Manager to update the email address for the player, though it's important to make sure your customer service representatives are trained to watch out for common social engineering tricks, so that they're only updating the email address of the actual owner of the account. SendAccountRecoveryEmail for that email address.In order for a player to recover their account, your game, website, or customer service can trigger: These options store username/email/password credentials with PlayFab directly. AddUsernamePassword is used to enable either/both of: LoginWithPlayFab and LoginWithEmailAddress.These indicate a few of the larger set of options available for recoverable login mechanisms. The focus of this tutorial is at the bottom of the preceding image, with the cells: AddUsernamePassword, LinkWithFacebook, or LinkWithGoogle.

Many players will only use these options again if they are attempting to recover their account, are using platform-specific features, or link a second Anonymous device.

An anonymous login is still relevant, and can continue to be the primary frictionless login for the player.
