## Short answer

NIP-07 describes a `window.nostr` interface that a browser extension or similar signer can expose to Nostr web apps. A site can request your public key or ask the signer to sign an event. The key advantage is that the web app need not receive your raw private key. Check permission prompts and the extension's trustworthiness before approving requests.
