You can use your username instead of your email to request a password reset. However, your email will be required to receive a confirmation code. If you set other recovery options such as a phone number, use it to recover your account.
If you joined TikTok with an account of another platform, you'll need to reset the password directly on that platform. For example, if you used Facebook, follow these instructions to reset your Facebook password. Once your account is recovered, you can log in to TikTok with your new password.
In case you're still unable to recover your TikTok account, submit a help request by following these few steps. Also, please note that CCM isn't affiliated with TikTok, so we can't recover your account here.
