I totally agree with WastingTime & everyone else who has made the point that having a passcode on your phone doesn't mean you have something to hide. My DH and I both already had email accounts before we met, FB accounts before we moved in together. Why on earth would we know each other's passwords? I can't even imagine any reasonable conversation in which either of us would ask to know the other's passwords or phone passcode. My work requires a passcode on the phone - it's an inherent part of the software which allows us to access work email on the phone. However, I already had a passcode on it - for security reasons, not to hide anything from my DH. It's my birthday so he wouldn't have to think too hard if he wanted to crack it. or he could just ask me & I'd tell him. But as I said, I cannot imagine asking another person for their password to something. I think the attitude that anyone who doesn't share phones, emails etc is not trustworthy or committed to their relationship, is the biggest load of bollocks I've ever heard. It's just that we are grown ups and trust each other without needing to see everything they do or say.
