How JSON Web Tokens Work
This guide is a work in progress. There's some useful information here while we make it more user friendly in the context of Feathers. In the meantime, here are a couple of resources on JWT to get more familiar with how it works, in general:
- The Auth0 JWT Documentation - If you want a good high-level overview.
- The IETF JWT Specification - If you want to get really technical.
Customizing the JWT Claims
firstname.lastname@example.org allows you to customize the data stored inside the JWT. We refer to the data in the JWT as the
payload. There are a few reserved attributes, which in the Official JWT Spec are called
claims. You can customize some of these claims in the JWT config options on the server. To get more familiar with the purpose of each
claim, please refer to Section 4 of the Official JWT Specification.
