Sometimes, it may be necessary to remove your ad account from a TikTok Business Center account. For example, when you have finished working with an agency or vendor, you may need to remove your ad account from their TikTok Business Center account.
You must be the owner of the ad account that you want to remove. Only the owner can change the relationship between an ad account and another TikTok Business Center account.
Log in to the TikTok Ads Manager as the owner of your ad account.
Click the user profile circle in the right top corner, go to Account Setting, and click Account Info.
Go to the bottom of the Basic Information page where you will find Permission Management.
Select the TikTok Business Center from which you want to remove your ad account and click Remove Permission.
Click Confirm.
