Gaming Project

Hello!

We are thinking of making a game, where we are going to use a arduinouno card, a server and client. We want the arduino to work as a verifier that compares the login info on the arduino with the login info from the server.
Our question is ! Do we have to get the login data from the server to the arduino to be able to compare or can we make a direct comparing in the server by getting the info to the server from the arduino to the server.

Thanks in advance!

both are possible!
but be aware the arduino has less ram to store login entries...
