Introduction

The Authentication with PlayFab is easy while versatile, having covered most leading platforms, namely HTML5 Web, Android, iOS, Desktop, Steam, Facebook, Instant Games, Xbox, PlayStation, Nintendo and more. It brings enterprise scaled account system features for your online games, into your Construct 3 and Construct 2 projects. ​ It supports both web and native implementations, with other additional tools in the collection to support each platform, including mobile and desktop, and consoles through 3rd party porting services.

PlayFab has one of the most important features you'll need for an online game, cloud save. Cloud Save automatically stores and manages the data of users in dedicated servers hosted by Microsoft Azure through their PlayFab service, while being accessible by multiple devices through multiple authentication methods for each account.

The Authentication object with PlayFab has support for almost all platforms. But in this particular discussion, we will focus in mobile development, since it commonly utilizes this feature.

As you can observe from the images above, there are these concepts called Switch Account and Bind Account.

These are implemented in the PlayFab Master Collection as plugins, which in order are the Authentication and Sync Manager plugins.

But before that, an explanation on the process of authentication and sync is necessary to make this easier to understand.

Initially, when an application connects to PlayFab, a one-time process account registration is recommended.

There are many authentication methods to choose from, one of them are Company, Android, iOS, Facebook, Google Play and Cryptography.

You can choose any initial authentication method for the user, but a registration without a player input is ideal for games.

The player can just proceed to link and secure the account after making a better bond with the game. This ensures you attract more users by not hassling them from forced login.

Registering through generated ids are common with web applications using the Custom ID authentication method.

However, on mobile the common way of registration for authentication is through the device id, either the Android or iOS login.

You can still use social networks like Facebook and Google, or your own company's allocated server account system, using the Email, Username and Password registration.

Although, it is essential that the registration process is effortless for the players.

Once initially registered, the player's account will be created. Then the player can add more authentication methods through the Sync Manager.

​

This enables the same account to be accessed with different account methods, this is called account binding.

If the player wants to switch to a different account, the player can simply login to one of the authentication methods of that other account. This is called account switching.

PlayFab's online account system functionality covering all aspects of online game features is without of doubt important but easy to use. It is a useful skill to learn for game development and your technical career.

The PlayFab Master Collection is a set of online tools you can use for any online game application, and it only requires a bit of learning. And you may always contact support if ever you are in need of assistance.

Sync Manager

The Sync Manager plugin goes hand in hand with the Authentication plugin.

When a user logs in with new credentials using the Authentication plugin. The plugin, by default and if enabled in the action, automatically creates the user a game account.

Please note that for email, username and password authentication, company registration is a signup action. For login, please use the company login action. Once a user has already registered and logged into an account, the user account can add more authentication methods through linking other login or signup methods, with additional login credentials such as social network account login links.

Therefore, allowing the account to secure more authentication methods to login with the Authentication plugin, and access the user account in different devices. ​ Once a new authentication method is linked to an account, the user can then log in through that ​newly linked authentication method using the Authentication plugin, to access the same account.
