Read each machine's ceiling on this page. Every machine is asked at once and each answer appears as it arrives. It is shown only: the dashboard cannot change it. To change one, edit /etc/vantage/config.toml on that machine.
To protect this app's key, press Move this Mac's key into the Secure Enclave. A key there cannot be taken off this Mac, even by someone who gets into it.
Read what it says, then press Move the key. The move runs machine by machine and shows its progress.
After the move this app has a new fingerprint on each machine.
Something not working?
A machine is listed as not answering: it took more than 5 seconds. Check that it is on and reachable, then press Check again; that asks only the machines that did not answer.
The move waits on a machine: it is unreachable. Check that the machine is on, then open this page again to see where the move stands.
This Mac has no Secure Enclave Vantage can use: the key stays in the keychain.
