I am new to Fuel PHP... I am working on a project with REST architecture in Fuelphp..... I didn't found any tutorial how to achieve the required functionality "User Authentication using Fuel PHP REST".
As REST server is stateless how do we use auth package of fuelphp in rest api?
As you also pointed, REST calls are somewhat stateless meaning you have no session to store.
The auth documentation has some methods which checks user credentials, but does not store authentication. There are no offical way of doing this.
