Im not sure if this is the right place for this post but I'm going to ask it anyways.

I just got a text saying that "*insert random numbers*" is my tiktok verification code, I have only created a tiktok account and used it once back in 2021 (I think?) and I haven't used the app since, it's not even on my phone anymore, yet I still got a verification code sent through my number, I have never put my password to anything out there, this means they know the password and username to my account, correct?

I assume this means they password guessed, if they did, is this something to worry about?

Would they have any personal information that I was required to put when signing up? I'm very anxious about the smallest of things, and I have no clue what they could and couldn't do, I have never posted anything on TikTok.
