Summary from the TLDR Web Dev newsletter

Token-based authentication is when a user is authenticated by presenting a digitally signed token instead of entering a password. It's a common alternative to session-based authentication. JSON Web Tokens (JWTs) are a popular implementation of token-based authentication as they have a self-contained structure that includes user data and a signature for integrity verification. This article provides code implementations for both generic token-based authentication and JWTs.
