Building a Secure Password Manager in Python (Part 1) | Authentication, Encryption & Menu

In this video, I build a complete password manager from scratch using Python.

This is NOT a beginner tutorial — this is a real-world project where we design, code, debug, and improve a secure credential vault step by step.

By the end of this video, we will have:
User account system
Login & authentication
Encrypted credential storage
A terminal-based password vault
A full menu system (Add, View, Delete credentials)
Multi-platform support (Google, Instagram, etc)

This is Part 1 of the FlexPass password manager series.

In the next video, we will improve the UI, add input validation, pagination, switching users, and more advanced features.
