The general crypto scheme (auth based on signed requests) is the same as SQRL. Differences: (1) SQRL employs one identity that users use across multiple SQRL-enabled services. Keyri-enabled accounts are not portable/natively-shareable across different services like that - they are specific to the services users registered with (2) Users don't need to download an SQRL client on their desktop device. I see that independent developers have made iOS and Android clients, but Steve notes they currently lack certain important features (though I haven't investigated enough to know their deficiencies) (3) Our main product is an SDK that developers can embed in their own mobile apps
