Hello,

are there any sample for Hiro + Unity using the email based authentication workflow? The default sample for Unity uses the Device Authentication.  
When I try to use `Client.AuthenticateEmailAsync`, neither session or account are set in the `NakamaSystem` and neither is the authorizer function called. Am I missing a crucial step?

Heya!

Just to clarify, have you tested the Hiro + Unity device authentication first to see if that works? Or did you start with email based?

Best,  
Nathan

Hi,

I started with email authentication as this was the previous worfklow from the pure nakama implementation.  
I will test hiro with the device authentication to see if that works 👌

Hello,

device authentication worked and I think I understand the workflow better now.  
But there is one issue: Is there a simple way to provide the email, username, password to the Authorizer function? Could you provide me an example for a email authentication based workflow for the NakamaSystem?  
I would really appreciate it.

Hello @kroonhorstdino,

I believe all you’d need to do is follow the example here: [Initializing the NakamaSystem - Heroic Labs Documentation](https://heroiclabs.com/docs/hiro/unity/getting-started/nakama-system/#configuration), but instead of using the deviceId, you’d grab the user’s Username and Password and then run `client.AuthenticateEmailAsync` instead of `client.AuthenticateDeviceAsync`.
