Random Password Generator Using Python

Introduction

Hey, python junkies we are here with another super exciting topic for a real-world cause. Keeping our online stuff is very important and to do that we have to set strong passwords. After going through this article, you will be able to make your password generator using Python, a flexible programming language, and Tkinter which is a user-friendly tool that makes things look good.

Below is the step-by-step guide for a fully developed random password generator using Tkinter

STEP-1: Importing the modules:

import random
import pyperclip
from tkinter import *
from tkinter.ttk import *

STEP-2: Defining the necessary functions for password generation, copying, and GUI interaction.

1. function for choosing password strength

def low():
	entry.delete(0, END)

	# getting the length of the password 
	length = var1.get()

	lower = "abcdefghijklmnopqrstuvwxyz"
	upper = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"
	digits = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789 !@#$%^&*()"
	password = ""

	# if strength selected to be low
	if var.get() == 1:
		for i in range(0, length):
			password = password + random.choice(lower)
		return password

	# if strength selected to be medium
	elif var.get() == 0:
		for i in range(0, length):
			password = password + random.choice(upper)
		return password

	# if strength selected to be strong
	elif var.get() == 3:
		for i in range(0, length):
			password = password + random.choice(digits)
		return password
	else:
		print("Please choose an option")
    # function for generating the password:
	def generate():
	password1 = low()
	entry.insert(10, password1)

	# function for copying the password to the clipboard:
	def copy1():
	random_password = entry.get()
	pyperclip.copy(random_password)

STEP-3: setting up the main function for creating the GUI window:

root = Tk()
var = IntVar()
var1 = IntVar()

STEP-4: creating the GUI components – Title, Labels, and Entry to show password generated and for length of password:

root.title("Random Password Generator")
Random_password = Label(root, text="Password")
Random_password.grid(row=0)
entry = Entry(root)
entry.grid(row=0, column=1)
c_label = Label(root, text="Length")
c_label.grid(row=1)

STEP-5: creating the GUI components – Copy Button which will copy the password to the clipboard and Generate Button which will generate the password:

copy_button = Button(root, text="Copy", command=copy1)
copy_button.grid(row=0, column=2)
generate_button = Button(root, text="Generate", command=generate)
generate_button.grid(row=0, column=3)

STEP-6: creating the GUI components – Radio Buttons for deciding the strength of the password while the default strength is set to medium:

radio_low = Radiobutton(root, text="Low", variable=var, value=1)
radio_low.grid(row=1, column=2, sticky='E')
radio_middle = Radiobutton(root, text="Medium", variable=var, value=0)
radio_middle.grid(row=1, column=3, sticky='E')
radio_strong = Radiobutton(root, text="Strong", variable=var, value=3)
radio_strong.grid(row=1, column=4, sticky='E')
combo = Combobox(root, textvariable=var1)
#Combo box for length of your password:
combo['values'] = (8, 9, 10, 11, 12, 13, 14, 15, 16,
				17, 18, 19, 20, 21, 22, 23, 24, 25,
				26, 27, 28, 29, 30, 31, 32, "Length")
combo.current(0)
combo.bind('<>')
combo.grid(column=1, row=1)

STEP-7: Running the GUI:
