Trust is very important in a relationship. It is one of the most essential factors of having a successful relationship. Some people are so close that they even share password information. Is that okay or going over the line?
Some people trust their significant others with information such as Passowords for E-mail, Facebook and Voicemail. They think that there is nothing wrong with giving that information away.
If someone trusts someone they don't need to know each other's passwords. Giving away a password is giving away privacy. You are giving that person access to go into your account when you are not around.
What happenes if you ever break up? He has that information and could hack into your account at any time.
When you sign up for Facebook, Twitter or anything that involves a password you need to know it and you only. You are given a password so only you could get into your account. If your loved one wants to know that information then he does not trust you. Be open with your loved one but don't give away too much information that you have no privacy. Just because you are in a relationship doesen't mean that you can't have your own life.
