Although the future of TikTok remains uncertain, the app continues to get new features. The latest is called Security Checkup, which is a centralized dashboard designed to help you protect your account.
You can find the tool by going to Settings and privacy > Security & permissions in the TikTok app. The idea behind Security Checkup is to make it easy for you to do things like link a phone number and email address to make sure you have a backup login method, turn on two-factor authentication, set up a passkey and enable biometric login options such as facial recognition.
