[PyGUI] Switching between two frames using Tkinter

[metulburr]

Put window 1 and 2 into separate Toplevel windows

import tkinter as tk
...
win1 = tk.Toplevel()

Then the login button would also include the command

win1.destroy

or into a function that did the login as well as self destruct, and load new window.
