## What it is
Master Password is a stateless password manager that derives unique site passwords on demand from a single master secret using a cryptographic algorithm, instead of storing them. The project has been renamed and rewritten as Spectre, and this repository is no longer actively maintained.

## Use cases
- generate unique passwords for every site without storing them
- manage passwords without a cloud vault
- recover my passwords from a single master secret
- offline password manager that never syncs
- replace my password manager with a stateless algorithm

## When to choose
- you want deterministic, stateless password generation with no stored vault
- you need apps across iOS, macOS, Android, and CLI
- you prefer open-source software with no cloud dependency

## When to avoid
- you need actively maintained software - use Spectre instead
- you want a traditional vault-based password manager with sync
- you need browser autofill integration from this legacy project

## Facets
- artifact type: application
- maturity: abandoned
- function: cryptography, security, cli
- domain: security, privacy, developer-tools
- platform: cli, cross-platform
- tags: password-manager, password-generator, stateless-passwords, scrypt, password-algorithm, moved-to-spectre, ios, macos, android
