Authenticator app doesn't work for me. I always get "invalid code", even though I entered the exact code. I tried QR Scan, Google Authenticator, and Microsoft Authenticator, but I always get the same message.

Does anybody knows how to fix this? I really wanted to secure my TikTok account because someone is attempting to hack my account, but they couldn't because it requires my mobile phone verification code. I got this message 8 hours ago, even though I never log out my TikTok Account. Why would someone try to hack my account? I only have 42 followers! 🙄 Also, I don't have even have many views on my videos! 🙄
