Let’s imagine a world where Alice needs to access some website or “Resource”. In a standard non-anonymous authentication flow, Alice needs to be granted authorization (a “credential”, such as a cookie) to do this. This grant can come either from the Resource itself (e.g., the website), or in other cases, from a third party (for example, Google’s SSO service.) For the moment we should assume that the preconditions for are not private: that is, Alice will presumably need to reveal something about her identity to the person who issues the credential. For example, she might use her credit card to pay for a subscription (e.g., for a news website), or she might hand over her driver’s license to prove that she’s an adult.
