Xtream Codes is generally more secure and reliable than raw M3U playlists because it hides internal stream URLs, protects credentials, allows device/IP limits, and enables better security controls like token-based authentication. M3U files expose your username, password, and entire playlist publicly, making them easy to steal. Xtream Codes also improves performance, supports faster navigation, and integrates better with modern IPTV apps. Glanfy recommends choosing providers that offer Xtream Codes API logins for better safety and stability.
