Introduction

As the world becomes more and more reliant on technology, cybersecurity becomes an increasingly important aspect of our lives. Passwords are a crucial part of our online security, but remembering multiple complex passwords for all of our accounts can be a hassle. This is where a personal password manager can come in handy. A password manager allows you to store all of your passwords in one secure location, so you only need to remember one master password. In this tutorial, we’ll show you how to code a basic personal password manager using Python.

Installing the Required Modules

The first step in creating your password manager is to install the necessary modules. We’ll be using the pyperclip module, which allows us to copy the password to the clipboard for easy paste. You can install it using the following command in your terminal or command prompt:

pip install pyperclip

Creating the Dictionary

The next step is to create a dictionary to store your account names as keys and passwords as values. Here’s an example of what it might look like:

accounts = {
    'email': 'aBc123#',
    'bank': 'p@ssword',
    'blog': 'qwerty'
}

Adding Accounts

We’ll start by creating a function to add new accounts and passwords to the dictionary. This function should prompt the user for the account name and password, then add them to the dictionary. Here’s the code for the function:

def add_account():
    account_name = input("Enter the name of the account: ")
    account_password = input("Enter the password: ")
    accounts[account_name] = account_password
    print("Account added successfully!")

Retrieving Passwords

Next, we’ll create another function to retrieve the password for a given account. This function should take the account name as an argument, retrieve the password from the dictionary, copy it to the clipboard, and return a message confirming that the password has been copied. Here’s the code for the function:

import pyperclip

def get_password(account_name):
    if account_name in accounts:
        password = accounts[account_name]
        pyperclip.copy(password)
        return "Password for '" + account_name + "' copied to clipboard."
    else:
        return "Error: Account not found."

Main Function

Now we’ll create a main function that prompts the user to either add an account or retrieve a password. Depending on the user’s choice, the function will call either the add_account or get_password function. Here’s the code for the main function:

def main():
    while True:
        choice = input("Enter 'a' to add an account, 'g' to get password, 'q' to quit: ")
        if choice == 'a':
            add_account()
        elif choice == 'g':
            account_name = input("Enter the name of the account: ")
            print(get_password(account_name))
        elif choice == 'q':
            break
        else:
            print("Invalid option, try again.")

Running the Password Manager

Finally, we’ll call the main function to run the password manager. Here’s the code to do this:

if __name__== 'main':
    main()

Conclusion

That’s it! You now have a basic personal password manager that you can use to store and retrieve all of your passwords. This tutorial only scratches the surface of what you can do with Python, but it should give you a good foundation for exploring more advanced topics. There are many other modules and libraries you can use to enhance your password manager, such as encryption libraries to keep your passwords safe from prying eyes. The possibilities are endless, so be creative and have fun!
