Log in userform with password

I have seen some good examples of userforms with a login name and password.

I have built up a userform to the point where I need help.

I would like the user to input their LOG IN NAME and PASSWORD (kept in sheet "UserRegister") in Column A and Column B. I want to ADD a column C with their division.

Based on their log in name, password, and division, I want to make visible certain sheets.

I have enclosed an example.

You can go directly to VBA to check it out, or the username is: joe and the password is: password
