Double-click the host to connect. The first time, Burrow shows the server’s host key fingerprint and asks whether you trust it.
Don’t just click through. The fingerprint is how you know you’re talking to your server and not to someone in between. Compare it with what the server admin gave you, or look it up on the server:
bash
ssh-keygen -lf /etc/ssh/ssh_host_ed25519_key.pub
If the two match, accept. Burrow remembers the key and only asks again if it changes.
What a changed key means, and what to do about it, is on the Known hosts page.
