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. ## Full article daily.dev links to this article rather than hosting it.
