A Password Manager for Ledger Devices

A simple password manager application for Ledger devices, with command-line interface similar to Unix pass. Works on Nano S, Nano S Plus and Nano X.

Up to 128 login/password entries can be stored. Passwords can be exported encrypted to a file, and imported on another device sharing the same seed.

This application is written in Rust and C.

Implementation details

Usage

The client script nanopass.py must be used to interact with the application to:

• list stored passwords,
• retrieve passwords,
• insert or generate new passwords,
• update or delete passwords,
• export passwords to a JSON file,
• import passwords from a JSON file.

The application can also be used with the dedicated chrome extension.
