Wow, what if I lose my mobile token in the battle? Net?

If the player loses his mobile phone security command, he should immediately go to Battle.net to change his password and change a new security command.

Players will not be able to log in to Battle.net because there is no security command. At this point, players can use secret email, secret phone and personal identity verification to log in and modify passwords.

Click "Unable to log in" in Battle.net login interface:

Then select Delete Security Order.

Then you can log in to fight. Net directly through the password, and then rebind the new security order.
