Developer Sessions is a Chrome extension developed by pal.sch84 that allows web developers to switch between different user sessions while developing web applications. This free extension is categorized under Browsers and falls under the subcategory of Add-ons & Tools.

With Developer Sessions, users can easily switch between different user sessions on the fly for applications that use the session-storage field `authenticationToken`. This is especially useful for developers who need to test different user scenarios and authentication states during the development process.

The extension provides a configuration page where users can define all their sessions, including the matching tokens (JWT). These sessions can then be activated with a simple click on the exception popup. Additionally, the extension offers a "Clear Session" feature that removes the `authenticationToken` from the session storage and the `JSESSIONID` from the cookies of the website.

Developer Sessions is a valuable tool for web developers who need to efficiently switch between user sessions while developing web applications. It simplifies the process of testing different user scenarios and authentication states, enhancing the development workflow.
