Alam mo ba ang password sa phone ni hubby?

My hubby do not have a password in his phone..But he knows my password and he knows that I need to put password on my phone coz all my financial accounts especially the apps are installed in my phone. The good things is if he need to borrow my phone and if I need to borrow his, we ask the permission of each other. No trust issues, it such that we always respect each others privacy of communication.
