It provides a user-friendly interface for verifying and decoding JSON Web Tokens (JWTs) directly in the browser. The extension offers a seamless experience with its intuitive design and straightforward functionality. It allows me to easily input a JWT and quickly validate its signature, expiration, and claims. The ability to decode the JWT and view its payload in a clear and organized manner is extremely useful for debugging and understanding the token's contents. I appreciate the additional features that JWT Checker provides, such as the option to customize the JWT secret, set expiration tolerance, and even support for different algorithms. These advanced settings give me more flexibility in handling various JWT configurations. Furthermore, the extension's compatibility with Google Chrome makes it convenient to use in my daily development tasks. It has become an essential tool in my toolkit, saving me time and effort when working with JWTs. Overall, JWT Checker is a fantastic extension that simplifies JWT verification and decoding. Its user-friendly interface, comprehensive features, and seamless integration with Chrome make it a must-have for developers working with JWTs.
