How to stop "Messages Agent wants to use the 'login' keychain. Please enter the keychain password" from occurring every time I turn my computer back on?

After I log into my computer, a popup always appears that says: "Messages Agent wants to use the 'login' keychain. Please enter the keychain password" and I have to enter it everytime before I start using my computer. I never use Messages ever, so its perplexing to me why this keeps appearing. Why does this happen and how do I stop it from popping up every single time I sign into my user.
