Domain ownership

Prove you control a domain.

Verifying a domain unlocks full secret-scan results for that host in your instant page check reports — without it, findings stay hidden so a stranger can't fingerprint your site's exposed keys just by scanning it. Publish one DNS TXT record to verify you control a hostname. DNS is controlled only by whoever administers the domain, so once a one-time value we generate shows up there, that's proof only you could have put it — nobody else can fake it from outside.
