PassRoot Seeded Password Generator

PassRoot is a seeded password generator that takes a master password, username, and domain name and spits out a secure deterministic password. You can also think of it as a stateless password manager.

You can check it out in webapp form at passroot.app!

This repository contains the source code for the webapp as well as a Linux CLI tool.
