Lesson 51 - Password Manager

This project stores passwords securely in a file and checks strength.


import json

import os


def check_strength(pw):

  return len(pw) >= 8 and any(c.isdigit() for c in pw)


passwords = {}

if os.path.exists("passwords.json"):

  with open("passwords.json") as f:

    passwords = json.load(f)


site = input("Enter site name: ")

pw = input("Enter password: ")

if check_strength(pw):

  passwords[site] = pw

  with open("passwords.json", "w") as f:

    json.dump(passwords, f)

  print("Password saved!")

else:

  print("Weak password. Try again.")
