Macaroons are a novel approach to authorization, based on cryptographic tokens that can be attenuated at any time by adding “caveats”. Introduced by a Google research paper in 2014, Macaroons have seen recent adoption by some cloud providers and OAuth2 servers.

In this session, we’ll describe in detail what Macaroons are, how they are implemented, and when they are useful. We will compare and contrast with other well-known standards such as JSON Web Tokens. Finally, we will look at some more recent token formats such as Biscuits that build on Macaroons.

Key takeaway

Learn when to use Macaroons vs other technologies for authentication tokens.
