TikTok Business Center is a central space to manage your business and advertising on TikTok. The email domain allowlist limits access to your Business Center to only members with an approved email domain.
You must be an Admin of the Business Center to add email domains to your email domain allowlist.
To setup an email allowlist:
Log in to your TikTok for Business account.
Click Business Settings.
In the Security section, click on Approved email domains.
Enter the approved email domain(s). You can enter various email options, such as xxx@tiktok.com.
Select whether you want this to apply to Admins or all members.
Click Confirm.
Note: If you have already added members outside of your approved email domains, you'll have the option to remove them at any time.
