Usermin is a web-based interface designed for users of the Webmin system administration tool. It allows non-technical users to manage their own settings and services without needing full access to the server. This makes it easier for individuals to perform tasks like managing email accounts, file storage, and databases. The interface is user-friendly and provides a simplified view of the available features. By using Usermin, users can customize their experience and access essential functions while maintaining security and control over the server environment. This helps streamline administrative tasks and enhances user autonomy.
