Platform-specifc sign-in

Platform-specific authentication

Platform-specific authentication (also called third-party authentication or external authentication) uses external identity providers. This means that you must create an identity provider configuration so that Unity Authentication can validate the player, making it possible to authenticate the same player from multiple devices.

When a player signs in through an external identity provider, a token is sent to Unity Authentication for validation. If the token is validated successfully by the external identity provider, the token is then associated with the PlayerID.

Below is an example of the flow when a user signs in with an external identity provider.
