What is the reason browsers do not store JWT tokens in the same manner as they do cookies?

Understanding the distinctions between a cookie and a JSON web token is crucial. With cookies, when the server includes 'set-cookie' in its response header, the browser automatically stores the cookie in local storage. Then, whenever the cookie is needed or for subsequent API calls, it is transmitted automatically. On the other hand, JWT tokens are sent in the response body. In this case, we need to manually save the token to local storage, retrieve it when necessary, and attach it to the request's header when making further requests to the server.

Could I be overlooking something here? I am seeking an efficient way to send the token to the client, have it saved and retrieved automatically, and then attached to requests similar to how cookies behave. Is there such thing as a 'set-token' response header, or could I simply transmit the token in a cookie? As a beginner who is just starting to learn, any guidance would be greatly appreciated. Thank you in advance.

Cookies are primarily designed for browser usage. If your application will solely be accessed through a browser, it is recommended to leverage cookies for their simplicity in setup and use.

On the other hand, JWT (JSON Web Tokens) serves as a more sophisticated solution tailored for API access. Although it can be utilized in browser-based applications, extra effort is required compared to using cookies.
