JWT versus PASETO

JWT and PASETO are both token-based authentication mechanisms for secure client-server communication. JWT is widely adopted but has security pitfalls like algorithm confusion attacks and complex configuration choices. PASETO was designed as a safer alternative with secure defaults, enforced modern cryptography, and simplified specifications to prevent developer errors. While JWT has better ecosystem support and adoption, PASETO offers improved security through its opinionated approach that removes insecure options.
