DAY CODING JOURNEY)

Continuing my coding journey (Day 1 remains unwritten, perhaps forever!), I'm tackling a real-time user verification program to deter unauthorized access. It's a seemingly simple idea, but hear me out.

Intended Functionality:

The program discreetly runs upon system startup, periodically (e.g., hourly) prompting for a password. Crucially, it maintains high priority, preventing closure or minimization. Incorrect password entry results in system shutdown.

<code class="language-python">from tkinter import *
import subprocess
import threading
import time
import getpass # Added for secure password input

window = Tk()
window.title("User Verification")
window.config(background="black")

# Initialize password (should be replaced with a more secure method)
q = getpass.getpass("Set initial password: ")

entry = Entry(window,
              fg='#00FF00',
              bg='black',
              font=('Arial',30),
              show='*') # Mask password input
entry.pack(side=RIGHT)

def verify_user():
    global q
    while True:
        y = entry.get()
        if y != q:
            subprocess.run('shutdown /s', shell=True)
            break  # Exit the loop after shutdown
        else:
            print('Verification successful.')
            # Replace password here (securely!)
            q = getpass.getpass("Set new password: ")
            entry.delete(0, END) # Clear entry field
        time.sleep(3600) # Check every hour

def start_verification():
    verification_thread = threading.Thread(target=verify_user)
    verification_thread.daemon = True # Allow program to exit even if thread is running
    verification_thread.start()

u = Button(window,
           text='Start Verification', # Changed button text
           fg='#00FF00',
           bg='black',
           command=start_verification)
u.pack(side=BOTTOM)


t = Label(window,
          text='Enter Password:', # Simplified label text
          font=('Arial',15),
          fg='#00FF00',
          bg='black')
t.pack(side=LEFT)

window.mainloop()</code>

Planned Enhancements:

This is a rudimentary version. Future improvements include:

• Dynamic Password Changes: Implement a secure method for changing the password after each successful verification. The current getpass module provides a start, but more robust password management is needed.
• Background Threading: The code now uses a daemon thread to run the verification process in the background, allowing the main window to remain responsive (though minimally so).

Disclaimer: This is a basic example and lacks robust security features. Use at your own risk. For production-level security, use established authentication systems. Suggestions welcome (but no guarantees of responses!).
