Why is my message locked in the game of crossing the line of fire

My information in Crossfire is locked, because the official CF game lock has been introduced to provide a safer game environment and prevent the player's CF game account from being stolen.

After the game lock is opened, the account will be forbidden to log in to the corresponding game, so no one can maliciously steal game equipment and game coins, which can ensure the safety of game property to the greatest extent.

Game lock supports "login-free" and "real-time logout", which can be used to lock your game account. It is a unique function of QQ Security Center (original mobile phone token), and both iPhone and Android phones can download and install the experience immediately.
