Is it one-time to scan the code and log in to the glory of the king?

After the the glory of the king game logs in, as long as the main player does not log in or the top player does not log in, the player can always log in. If the second device is already logged in, you will not be able to log in.

That is to say, the gamer can always log in to the account after scanning the code, but only if the gamer does not log out of the account and the account is not logged in elsewhere. If the player cancels the account or logs in elsewhere, it is necessary to scan the code again.
