Implementing JSON Web Tokens (JWTs) in Python

A JSON Web Token is an access token standardized in RFC 7519 that enables secure data exchange between two parties. This token contains all the important information about an entity, which means that there is no need to query a database or save the session on the server. A JSON Web Token offers several advantages over the traditional cookie authentication and authorization method, so it is used in the following situations:

REST applications: In REST applications, the JWT guarantees statelessness by sending the authentication data directly with the request.
Cross-origin resource sharing: The JWT sends information using cross-origin resource sharing, which gives it a great advantage over cookies, which are not usually sent using this procedure.
Use of many frameworks: When multiple frameworks are used, authentication data can be shared more easily.
