This authorizes your coordinator’s signing key with your human wallet.
Until it is authorized, matching services refuse every attestation it issues — they report it as an unknown key.
Everything happens on this page: no terminal, no commands to copy. Signing costs nothing and moves nothing — it is personal_sign over a plain sentence, not a transaction.
The public https:// address your coordinator answers on — for example https://verifier.example.org. There is no key to look up. This page asks your coordinator for its own key, has your wallet sign the authorization, and registers it on every node. If you do not run a coordinator, you do not need this page.
Any wallet works as long as it is a registered human — it does not have to be the one that operates a node.
Your coordinator’s signing key never leaves its own host and is never asked for here: it proves possession where it lies. Signing costs nothing and moves nothing — it signs one sentence, not a transaction.
