Am I (F32) in the wrong for not deleting my tiktok after husband (M33) put a password on his phone?

My husband (M33) put a password on his phone for the first time. I felt like it was a big deal because I could previously go through his phone whenever and see anything I wanted. (Before anybody assumes he was hiding anything, he wasn’t and I never found anything I didn’t already know about him on his phone). I even used to accidentally pick up his phone and realize it was his instead of mine when we were out at a restaurant or something. He’s put a passcode on it now, and I feel weird not knowing what’s going on his phone. I still don’t think he’s hiding anything but I still don’t like the lack of transparency between us now. I made a Tiktok on tiktok about the situation and a comment said “Delete your tiktok, it’s a red flag”. I don’t know why my Tiktok would be a red flag, but I’m just wondering what other men think about the situation. I’m the type to be super transparent and just let people look through my phone and stuff like that but I understand not everybody is like that.
