Advertisers can opt-out their TikTok Ad Manager account from using Autofill. In this case, end-users will not have the option to use Autofill for the web pages linked within the ads from that opted-out account. To opt out of Autofill through email, send your request to autofill.support@bytedance.com with your account ID. We will turn Autofill off for any web pages linked with ads from the opted-out account.
Note: Requests could take up to one week to process.
