Anonymous File Transfer Protocol (FTP) allows remote users to access an FTP server without the requirement of a specific user ID or password. By using the default username "anonymous" and optionally providing their email address as the password, users can connect to the server and access a designated directory containing publicly available files.
Anonymous FTP is commonly utilized for distributing files such as software updates, documentation, or public data. However, it usually imposes restrictions on write or upload privileges to ensure security. Users can access anonymous FTP servers through FTP client software or web browsers supporting FTP functionality.
