The protocol uses DNS delegation, SD-JWT tokens with key binding, and browser mediation to enable mail domains to delegate verification to an issuer. The browser requests a token from the issuer using authentication cookies, verifies it, and provides it to the web application. This approach enhances privacy by preventing issuers from learning which applications users are accessing, while eliminating the friction of traditional email verification flows that cause user drop-off. ## Full article daily.dev links to this article rather than hosting it.
