@katiebug10 Hi and welcome you would just need to sign in and out of your separate king accounts, the problem sometimes arises when the accounts get merge, but there is no way of knowing in advance if this would happen. Also possible to recover account if it does
Hope this helps
Welcome to the King Community.
Since you and your sister are playing the game on the same PC then the best way is different browser. In case of Kingdom Platform you need to log out from homepage (for same brower)
If you are playing the game through the same app then you have to follow the steps above which Kiara has already given you.
