Generate a keyfile containing an access token derived from a secret specific to your user account and securely signed with an elliptic curve algorithm using a master key to prevent forgery. Keyfiles may be encrypted with a secondary passphrase for additional security.
Connect to any game (or other) service for the TI-84+ CE that supports TInyAuth and your credentials are extracted from your keyfile with no user input required.
Service developers can use CryptX to extract credentials on the client and a simple POST request on the server to authenticate user credentials with TInyAuth.
