On first launch the app derives a unique key from your machine. Paste it here while the app is running to open your dashboard — the app confirms the sign-in on its own. If you lose the key, launch the app again — it shows the same key. No email, no password.
Or press “Open dashboard” in the app — it signs you in directly.
Your key stays on your computer. We store no email, no password, and nothing that could identify you.
