  • Login Lockout: Locks access after multiple failed authentication attempts.

Technologies Used

  • Python 3.12
  • CustomTkinter: Modern and customizable graphical interface.
  • PyMongo: Integration with MongoDB.
  • PyCryptodome: For message encryption and decryption.
  • Plyer: For system notifications.
