Compare this Ed25519 fingerprint before accepting the host key:First connection
ssh cool.computer opens your account shell, the same cool> prompt as running cool by itself. You don’t need the Cool Computers CLI.
OpenSSH proves your selected public key. Cool Computers then asks for your email address and a six-digit code, and signs you in or up. After verification, that key is bound to your account and later connections open the shell directly. The SSH username is ignored. While Cool Computers is full, an email with no account and no invitation joins the waitlist, and the shell says so instead of opening.
Choose a key
OpenSSH offers identities in order. If you have several keys, select the one you want Cool Computers to bind:ssh-keygen -t ed25519 if you don’t have one.
Windows
On Windows 10 build 1809 or later and Windows 11, run the same commands from PowerShell or Windows Terminal. Ifssh is missing, install the OpenSSH Client optional feature in Windows Settings.
Limits
ssh cool.computer only runs the account shell. It does not accept remote commands, file transfer, or forwarding. To work inside a computer with a VM, use cool enter bakery or cool ssh bakery.
The cool.computer SSH endpoint is IPv4-only.
