SQRL Diagnostics


GRC's SQRL Diagnostics System

This SQRL diagnostics facility is intended to aid anyone implementing a SQRL client to exercise their protocol implementation against GRC's standards-compliant server. After a multi-loop authentication completes (and also when it doesn't for any reason) the diagnostics page will present a detailed analysis of the data exchanged, including its full cryptographic breakdown.

Note: If you are experimenting with GRC's SQRL client for Windows, you must run it at least once so that it can register itself to pop-up when SQRL's QR codes are clicked in the web browser.

To provide to SQRL's diagnostics system, refresh this page or press the button below.
