Sign-in is switched off. The hosted cockpit is being rebuilt, so there is no account to sign in to right now — not a password problem, and nothing you did.
The engine underneath is open source and works today. You can run the whole thing on your own machine with your own key — no waiting on us.
“Get told when it reopens” is GitHub’s own release notifications — watch the repo and you’ll hear when the hosted cockpit is back. There’s no email list to join yet, so we’re not going to ask for your address and then lose it.
