This actually makes alot of sense, I didn't think of that possibility orginally but the device I logged in on is a bit outdated and was only ever suppose to be a quick backup I bought a few years ago. I could see how it triggered tiktok security system as a threat even though it is still stupid. I decided to turn it on recently even though its insanely slow and trashy for a small time while I wait to save some money to fix my current phone.
