what does it mean when girlfriend gives her password to her boyfriend?

i just want to know from people here , i am talking about who are dating , what does it mean for you when some girls give their password to their boyfriends and let them check their messages
are those girls weak and manipulated by their boyfriends
or they are so much honest they just want to show and prove that they are not hiding anything from their boyfriends
share what you think

thanks
