MultiPass is a Firefox extension designed for web development that simplifies the process of handling HTTP basic authentication. With a subscription-based license, this tool allows users to register credentials associated with specific regular expressions. As you navigate different websites, MultiPass automatically detects when a URL matches one of your predefined expressions and seamlessly sends the corresponding credentials. This functionality eliminates the hassle of manual login prompts, providing a smoother browsing experience.

The extension is particularly useful for developers or users who frequently access multiple sites requiring authentication. By automating the login process, MultiPass enhances productivity and minimizes interruptions during web development tasks. Its straightforward approach to managing credentials ensures that users can focus on their work without getting bogged down by repetitive login procedures.
