Tengen – Self-hosted, open source password manager with local encryption

Summary: Tengen is a self-hostable password manager that keeps all data encrypted and stored locally on your machine, never sending passwords to third-party servers. It uses a React, FastAPI, and SQLite stack, with full source code available for auditing and no telemetry or subscriptions.

What it does

Tengen encrypts your password vault at rest and runs entirely on your own device via a single docker-compose setup. It integrates with Have I Been Pwned (HIBP) to check for exposed passwords and performs security scans on every commit using tools like Gitleaks, Bandit, Semgrep, and pip-audit.

Who it's for

It is designed for users who prioritize privacy and want full control over their password data without relying on cloud services.

Why it matters

Tengen addresses concerns about cloud-based password managers by ensuring sensitive data never leaves the user’s network, enhancing security and trust through transparency and self-hosting.
