Should I be concerned?

Anonymous
About a year ago, I found out that my fiance was still in contact with his ex everyday via whats app videos calls. Also, she was sending him selfies of herself. He apologized and asked for another chance which I gave him. We are suppose to be getting married next month but I hate how secretive he is with his phone. Am I wrong for wanting to know his password? I don't want to search through his phone but I will feel a lot better if I knew it after what happened. If I ask him to make a call from his phone, he unlocks it and goes on the phone app to dial the number. After the whole thing with his ex I asked him to see his phone randomly and he got angry. Also, it had a time he started putting his phone on silent whenever he was around me, he doesn't do it anymore but these are the reasons that I will feel a lot better if he was more open with his phone. If I address this issue, he is just going to change the topic or say, I'm just bringing up the past and I should focus on the future. What should I do? Am I being unreasonable?
