Alternatively you could put a panel inside the user control, but around it's content and then set the visibility of that panel within the controls codebehind depending on whether the username and password are valid or not. That way the hiding/showing of the control is completely handled by itself and requires no extra code outside of the control.
Do you want UserControl to appear by default? Or are you looking for the way this site (EE) as login implemented?
The above given suggestions are correct, though if you want control to display on click of a link as on EE, you might wana go for JavaScript for hiding this control.
You will need to set - panel.style.display = "none".
Something like below:
Yes, doing this client side is something to consider.
I did consider javascript, but when I read "If the user successfully authenticates, I want to hide the control after the page refreshes." in the question I guessed the authentication was being done server-side, which is why I suggested the modification of the panel.Visible property in the codebehind.
But you could do it client-side, maybe even with an Ajax call for the authentication, depends if you want to go down that route.

Do you have the relevant section of the html source? is this vb, c#, c++?
You could wrap the user control in an asp:panel and change the .visible property of the panel in the codebehind.
HTML:
--------
<asp:panel id="panel1" runat="server">
<my:UserControl ... runat="server"/>
</asp:panel>
Page.aspx.vb (for example)
--------------------------
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If (IsPostBack) Then
If (<check if user has authenticated ok from username and password in user control>) Then
panel1.Visible = False
End If
End If
End Sub
