JSON Web Tokens (JWTs) are widely used for secure data exchange due to their digital signing and verification capabilities. However, proper implementation is crucial, as misconfigured JWTs can lead to significant security risks. Developers must follow best practices to prevent vulnerabilities, such as validating token claims and preventing token tampering. Industry guidelines and frameworks, like OWASP, provide valuable resources for secure JWT implementation. As an alternative, other authentication methods like OAuth or session-based authentication should be considered, weighing their trade-offs in terms of security, usability, and complexity. Proper evaluation is necessary to choose the most suitable solution.
