Use this tab to grant or revoke that permission. * **Add player**: opens a small form where you enter the player's **Identifier** and an optional **Label**, then confirm. They can immediately buy a domain from the app. * **Delete** (trash icon): removes a player from the whitelist, revoking their ability to buy new domains. {% hint style="info" %} This only affects buying **new** domains. Domains a player already owns stay theirs even if you remove them from the whitelist. {% endhint %}
