Essentially, this is about red flags and sharing passwords/phone passwords.

Do you think that you'd want to keep your own things private but are open to a spouse/ltr partner to asking to check sometimes or borrowing your phone?

Or do you believe in open-phone policies where if someone doesn't want to do that, you'd view it as a red-flag?

Also for married people who may claim that things are different on this topic when it comes to marriage, when, how and why?

Personally I want to respect the privacy of others and have my own privacy respected.
