Choose two verification methods
- In TikTok, tap Profile → Menu ☰ → Settings and privacy.
- Open Security & permissions → 2-step verification.
- Select at least two methods, including Authenticator and another available option such as Phone or Email.
- Complete each method’s prompts and tap Turn on to confirm.
Add TikTok to Sign In
Use Sign In, our authenticator app, for verification codes on your iPhone.
- On TikTok’s authenticator enrollment screen, copy the setup key.
- Open Sign In and tap Add → Enter Setup Key. Set Service to TikTok, Account to your username, and paste the secret into Key.
- Review the entry and tap Add Account.
- Return to TikTok and enter the current code to confirm.
If the QR code is displayed on another screen, you can instead use Add → Scan QR Code. Keep the setup key private.
Keep a recovery method
Save any recovery code supplied during enrollment securely outside your phone. If you lose authenticator access, choose Can’t access the app and follow TikTok’s recovery-code instructions. Use Need more help? if that code is also unavailable; identity verification may take time.
Phone and email verification depend on continued access to those contact methods. Keep both secure and up to date.
If a code does not work
Make sure the TikTok entry in Sign In matches the account you are using. Wait for a fresh code, then enter it before it changes. If fresh codes keep failing, check that your iPhone uses automatic date and time.
Keep a working sign-in session and your recovery information available while resolving the problem. Adding an entry to Sign In does not finish enrollment: the service must accept a code and confirm activation.
