Welcome folks today in this blog post we will be building a password manager which generates random passwords and stores the credentials inside a text file on your computer using random library. All the full source code of the application is shown below.

Get Started

In order to get started you need to make an app.py file and copy paste the following code

app.py

# Python program to generate random
# password using Tkinter module
import random
from tkinter import *
from tkinter.ttk import *
from tkinter import messagebox
# Function for calculation of password
def low():
    entry.delete(0, END)

    # Get the length of passowrd
    length = var1.get()

    lowSecutiy = "abcdefghijklmnopqrstuvwxyz"
    mediumSecurity = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"
    highSecurity = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*()"
    password = ""

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

    # if strength selected is medium
    elif var.get() == 3:
        for i in range(0, length):
            password = password + random.choice(mediumSecurity)
        return password

    # if strength selected is strong
    elif var.get() == 0:
        for i in range(0, length):
            password = password + random.choice(highSecurity)
        return password
    else:
        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 save():
    url_target = url.get()
    Username = user.get()
    random_password = entry.get()
    f= open(Username+".txt", "a+")
    f.write("Your targeted URL: "+url_target+"\r\n"+"Your UserName: "+Username+"\r\n"+"Your Password: "+random_password+"\r\n")
    messagebox.showinfo("Credentials Saved", "Your Credentials are saved.")
# Main Function

# create GUI window
root = Tk()
var = IntVar()
var1 = IntVar()
# Title of your GUI window
root.title("Random Password Generator")
# TYPE URL
url_target = Label(root, text="URL")
url_target.grid(row=0)
url = Entry(root)
url.grid(row=0, column=1)

#TYPE USER name
Username = Label(root, text= "UserName/Email")
Username.grid(row=1)
user = Entry(root)
user.grid(row=1, column=1)

# create label and entry to show
# password generated
Random_password = Label(root, text="Password")
Random_password.grid(row=2)
entry = Entry(root)
entry.grid(row=2, column=1)

# create label for length of password
c_label = Label(root, text="Length")
c_label.grid(row=3)

# create Buttons Copy which will copy
# password to clipboard and Generate
# which will generate the password
copy_button = Button(root, text="save", command=save)
copy_button.grid(row=4)
generate_button = Button(root, text="Generate", command=generate)
generate_button.grid(row=2, column=2)

# 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=3, column=2, sticky='E')
radio_middle = Radiobutton(root, text="Medium", variable=var, value=3)
radio_middle.grid(row=3, column=3, sticky='E')
radio_strong = Radiobutton(root, text="Strong", variable=var, value=0)
radio_strong.grid(row=3, 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('<<ComboboxSelected>>')
combo.grid(column=1, row=3)

# start the GUI
root.mainloop()

Now if you run the python script by typing the below command as shown below

python app.py
