## AI overview

This article explains what JSON Web Tokens (JWTs) are, how digitally signed JSON objects enable parties to verify transmitted information, and why JWTs became widely used for stateless authentication. It also connects JWTs to Neon RLS and Postgres authorization, and describes their benefits for cross-domain compatibility, scalability, flexibility, and security.
