Eternal Tower has a game account, which will send text messages every time you log in.

Oh! Is it login game SMS verification?

You can go to Shanda online to modify it, and the security option is no problem. Another security measure is to log in to the game with a security card. This way is more troublesome, but if there are high-value items in the game, take them!

After all, safety first?

This function of Shanda is to protect the security of the player's account!

If it's too much trouble, change it! !

Personally, I suggest not to change it.
