Python Password Manager

Password manager is a tool to save user credentials for various websites and store them in an organized way easy to view and manage by the user. It also helps the user generate a strong password so your credentials are always strong and secure.

Language practices within this project:

• Tkinter library

• GUI with Tkinter

• OOP

• Keyword arguments with '**kwargs'

• Lists, dictionaries, loops

• Random password generation

• List comprehension:

      password_letters = [random.choice(LETTERS) for _ in range(random.randint(8, 10))]
      password_numbers = [random.choice(NUMBERS) for _ in range(random.randint(2, 4))]
      password_symbols = [random.choice(SYMBOLS) for _ in range(random.randint(2, 4))]

• Working with CSV files using Pandas library:

  • Creating a CSV file:

        if not os.path.isfile("book.csv"):
            file = pd.DataFrame(columns=["id", "website", "username", "password"])
            file.to_csv('book.csv', index=False)

  • Reading the data from the CSV file:

        df = pd.read_csv('book.csv', index_col=0)
    
        for index, row in df.iterrows():
            # set each record from the data file to a parent value and credentials under it in the tree
            parent_id = self.bw_list.insert('', 'end', text=f'{index}. {row['website']}', values=([f"-{index}"]))
            self.bw_list.insert(parent_id, 'end', text=f"User: {row['username']}", values=(["+"]))
            self.bw_list.insert(parent_id, 'end', text=f"Password: {row['password']}", values=(["++"]))

  • Saving new data to the CSV file:

        data_strct = {
                "website" : [self.website.get()],
                "user" : [self.user.get()],
                "password" : [self.password.get()]
            }
    
        # read the last index of the last row or set the index to zero if there are not records
        existing_df = pd.read_csv('book.csv', index_col=0)
        if existing_df.index.empty:
            last_index = 0
        else:
            last_index = existing_df.index.max()
    
        # save the data from the app fields to the csv file
        new_data = pd.DataFrame(data_strct)
        new_data.index = range(last_index + 1, last_index + 1 + len(new_data))
        new_data.to_csv('book.csv', mode='a', header=False)
