An alternative perspective is that "theUser" should not know how to
"authenticate" itself.
Rather, you might have an "Authenticator" that knows how to do
everything that has anything to do with authentication, which can be
passed the un/pw.
"theUser" might have some kind of state ("isAuthenticated"), but even
there you might ask the Authenticator (or some other
authentication-related state checker) rather than coupling notions of
authentication with theUser itself.

Why do you need a method to a login screen? Wouldn’t a login screen be
more of a display compared to a logic object?
You need to think about the objects involved, rather than the processes.
You have a user… What does that user want to do? Authenticate, or Login.
Object = theUser
Method = public Authenticate(Login, Password) as Bool
This way, you can “ask” the user if they are logged in when you need to
check the authentication of a certain page. This user object can also
hold their name, email, access keys, if they are authenticated, their
login, etc..
So, I would have the following in the page that the login form posts to :
*If (theUser.Authenticate(form.login, form.password))*
*{*
* // login is good, do what we need to do here*
*}*
*Else*
*{*
* // login is bad. Tell the user and re-ask for username / password here*
*}*
Hope this helps, at least a little bit.

*Subject:* [CFCDev] OOP and creating a login section
Hi everyone,
When I'm trying to move to a more OOP style of building CF applications,
I always find that when it comes to building sections like a login
section or a message recording form, I can't relate OO to it. When I
read examples in both Java and CF they are always cars, people or
animals. I find it hard to turn the idea of having properties and
methods to a login screen. Then I find I fall back into procedural
programming.
How do those who do use OOP create login screens or forms?
Stephen
