I asked for his phone passcode and he said no?

Anonymous
Me and my boyfriend were playing around and he took my phone because I was playing on it a lot and put it in an area I couldn’t reach. In response I took his phone and was holding it then I asked for his passwords and he said no. I asked again, he would not give it to me. Later I asked why a few times and he gave me a different reason each time:
1. the first time he said he had a surprise he didn’t want me to see
2. the second time he asked for my passcode, when I told him he said his quickly and when I said I thought it was weird that he didn’t just say it the first time he stuttered a lot and eventually said he didn’t know it would impact me (and that it’s not normal for a girlfriend to be impacted by something like that) and that he said no out of habit

This is coming some time after for my birthday he put me on his close friend story saying happy birthday and when I asked why he said he wanted to keep his life and good things private.

What do you guys think?

Okay I just reread the question and realized I typed “passwords”. I meant I asked for his phone passcode. That’s one singular password not multiple passwords. If this changes your answer let me know.
