How to Build Password Generator Using Python GUI | 3 Steps CodeHelping

In this blog, I will share how you can also build your own password generator using Python. Even if you just started coding in Python, you can do this.

We will use a simple library called Tkinter to create the GUI, along with two other Python libraries: random and pyperclip.

What Tools We Will Use

To create this Password Generator using Python, you must have Python installed on your computer. If not, you can download it from the official Python website.

Now let’s look at the three libraries we will use:

Tkinter – This is a built-in library in Python. It helps you make GUI (Graphical User Interface). You can create windows, buttons, labels, text boxes, etc., using Tkinter. It comes with Python, so you don’t need to install it.

random – This is another built-in library. It is used to pick random things. In our app, we will use it to randomly pick letters, numbers, and symbols to create the password.

pyperclip – This library helps you to copy text directly to your clipboard. So after the password is created, you can press a button to copy it. You need to install this one by typing:

install pyperclip

Logic Behind Password Generator

The app will have a simple window with a button to generate a password. You can also see the password in a text box.

There will be another button to copy the password. When you click “Generate,” a strong random password will appear. When you click “Copy,” the password will be copied to your clipboard.

This might sound big, but trust me, it’s not hard at all. Let’s now see the full code step by step.

Full Python Code for Password Generator Using Python

import tkinter as tk
import random
import pyperclip

def generate_password():
    characters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*()?"
    password = ""
    for _ in range(12):  # You can change the number for longer passwords
        password += random.choice(characters)
    password_entry.delete(0, tk.END)
    password_entry.insert(0, password)

def copy_password():
    password = password_entry.get()
    pyperclip.copy(password)

# Create main window
root = tk.Tk()
root.title("Password Generator")
root.geometry("300x200")

# Add entry box
password_entry = tk.Entry(root, width=25, font=("Arial", 14))
password_entry.pack(pady=20)

# Add buttons
generate_button = tk.Button(root, text="Generate Password", command=generate_password)
generate_button.pack(pady=5)

copy_button = tk.Button(root, text="Copy to Clipboard", command=copy_password)
copy_button.pack(pady=5)

# Start the GUI
root.mainloop() 

How to Run this Code ?

Save the file and run it using Python. A small window will appear. When you click the “Generate Password” button, a new password will show in the box.

This is how easy it is to create a working app using Python. It may look small, but it teaches you a lot about GUI, random functions, and using external libraries like pyperclip.

Final Thoughts

When you are in your first year of college, it’s normal to feel lost or confused while coding. I was the same. But building small projects like Weather App using Python and liken this one: Password Generator using Python gives a lot of learnings.

This password app may look small, but it is powerful. It gives you real output, you can click buttons, and it feels like a real tool.
