Python | Random Password Generator using Tkinter

  • Difficulty Level : Medium
  • Last Updated : 13 Apr, 2021

With growing technology, everything has relied on data and securing these data is the main concern. Passwords are meant to keep the data safe that we upload on the Internet. 
An easy password can be hacked easily and all the personal information can be misused. In order to prevent such things and keep the data safe, it is quite necessary to keep our passwords very strong.
Let’s create a simple application which can randomly generate strong passwords using Python Tkinter module.
This application can generate random password, with the combination of letters, numerics, and special characters. One can mention length of the password based on requirement and can also select the strength of the password.
Modules needed: 

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

Below is the implementation: 


# Python program to generate random
# password using Tkinter module
import random
import pyperclip
from tkinter import *
from tkinter.ttk import *
# Function for calculation of password
def low():
    entry.delete(0, END)
    # Get the length of password
    length = var1.get()
    lower = "abcdefghijklmnopqrstuvwxyz"
    upper = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"
    digits = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789 !@#$%^&*()"
    password = ""
    # if strength selected is low
    if var.get() == 1:
        for i in range(0, length):
            password = password + random.choice(lower)
        return password
    # if strength selected is medium
    elif var.get() == 0:
        for i in range(0, length):
            password = password + random.choice(upper)
        return password
    # if strength selected is strong
    elif var.get() == 3:
        for i in range(0, length):
            password = password + random.choice(digits)
        return password
        print("Please choose an option")
# Function for generation of password
def generate():
    password1 = low()
    entry.insert(10, password1)
# Function for copying password to clipboard
def copy1():
    random_password = entry.get()
# Main Function
# create GUI window
root = Tk()
var = IntVar()
var1 = IntVar()
# Title of your GUI window
root.title("Random Password Generator")
# create label and entry to show
# password generated
Random_password = Label(root, text="Password")
entry = Entry(root)
entry.grid(row=0, column=1)
# create label for length of password
c_label = Label(root, text="Length")
# create Buttons Copy which will copy
# password to clipboard and Generate
# 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)
# Radio Buttons for deciding the
# strength of password
# Default strength is 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.grid(column=1, row=1)
# start the GUI
