How to prevent two root windows from coming up when I start Tkinter?

Question

How can I hide the two Tkinter root windows that are popping up in my program? I have tried to use root.widthdraw(). Here is a link to my Pastebin.

Background

I am trying to create a really basic email client to learn more about Tkinter and SMTP. I have decided that my program will first create a Toplevel window where the user will enter their credentials, and if the Server can authenticate them, then the program opens the email send dialogue. Annoyingly, I have not been able to hide the 2 other root windows which open when the program starts up. I have attempted to use root.widthdraw() to avoid this issue.

Relevant Code

#-----Authen is a toplevel class-------------

passcheck = Authen()

root = Tk()
root.mainloop()
root.widthdraw()

You should create your root window before creating any other windows. Otherwise you get exactly what you observe: Tkinter will automatically create a root window the first time you create some other widget, and the you are creating a second one.

I'm running Python2.7, with the default tkinter package, and my root object doesn't have a withdraw() method. Besides that, you can also just run mainloop off the toplevel called passcheck and it'll save you a window. 

class Authen(Frame):
    def __init__(self, master):
        Frame.__init__(self, master)

then: 

root = Tk()
passcheck = Authen(root) 
root.mainloop()

edit: Here's a solution, instead of Authen being a TopLevel, have it be a Frame instead, and pass root as it's master. http://pastebin.com/TtnvU0er
