Reconnect the browser signing key with the Smart Vault owner wallet.
Sign in with the Smart Vault’s owner wallet and open My Smart Vault. If the key cannot be checked, use Retry first. Only when the app confirms that a new key is needed should you choose its signing-key setup action and approve the request.
A replacement updates the existing vault’s authorized play key and may replace another device’s key. Wait for registration to finish and for the app to show that this browser has the registered key. If the change is unconfirmed, check that attempt before starting another. Never share a signing key or owner-wallet secret.
