🔒 Lock: A Local UI-Based Password Manager

TL;DR • Key Features • Quickstart • Credits • License

Lock is a local password manager with a sleek CustomTkinter GUI.
It encrypts all your credentials with a master password, so you only need to remember one password to access them all.
Simple, reactive, and cross-platform — security made user-friendly.

• Minimal setup – just run and start managing passwords
• Secure by design – AES encryption tied to your master password
• Smooth UI – reactive CustomTkinter interface with password-hiding features
• Curated visuals – themed with the elegant Nord color palette
• Cross-platform – works on Windows, macOS, and Linux

• Simple GUI – Start the app and you’re ready to go.
• Reactive UI – Every action instantly updates the interface.
• Password Safety – Hide input while typing and store securely.
• Design Principles – “Remember one password, access all.”
