Yes. Xtream Codes API logins are generally safer because they hide your real streaming URLs, prevent exposure of the entire playlist, and allow providers to enforce device/IP restrictions. M3U playlists are easily leaked, copied, shared, or stolen, especially when the URL contains username and password in plain text. Xtream Codes also supports token expiration, session control, and rate-limiting. For stronger protection, providers listed on Glanfy use short-lived tokens and encrypted HLS URLs.
