My Mac keeps asking for my "login" keychain after I changed my password on my Mac. How do I stop the popups?

I forgot the password to my Mac, so I reset my password, and ever since then, there have been popups asking for my "login" keychain password. I enter it every time, but they still pop up. Also, my Mail keeps asking for the password to my email, and iMessage is on, but I can't receive any messages, and the window won't even pop up.

Does anyone know the solution for this?
