Keychain password
I reset (changed) my daughter's user password while logged in as admin. Also made some changes in parental controls for her. When I went back in as her and launched Safari I was asked for my keychain password. Assuming it is the same as the admin login password I entered it. It was not accepted ... several times. I was able to sort of okay around it but I don't know exactly what didn't happen by not entering it, nor do I understand why it wasn't accepted. Did I assume correctly that the keychain and admin login passwords are one and the same?
