Hint

🧠 Not sure where to start?

Start by thinking about how to store user credentials. A simple way is to use a JSON file like this:

{
    "admin": "pass123",
    "user1": "mypassword"
}

You can use Python’s json module to read and write to that file.

Next, build a basic login GUI using Tkinter. Create text entry boxes like this:

username_entry = tk.Entry(root)
password_entry = tk.Entry(root, show="*")  # hides password input

Then, add buttons for login and registration. When the user clicks the login button or presses Enter, check if the username and password match what’s stored in your file.

To detect Enter key presses, bind it to the login function like this:

password_entry.bind("<Return>", login)

When login is successful, hide the login window with:

root.withdraw()

And open a new one using:

tk.Toplevel()

That’s how you simulate a page switch!
