Self Hosted Password Managers

This project provides a comprehensive, self-hosted platform for zero-knowledge credential management and enterprise secrets orchestration. It functions as a secure vault that ensures all encryption and decryption processes occur exclusively on the client side, preventing the server from ever accessing plaintext data. By combining identity federation with robust access controls, the system enables organizations to centralize the management of passwords, passkeys, and sensitive infrastructure credentials. The platform distinguishes itself through its focus on both human-centric security and aut

Passbolt is an open-source, self-hosted password manager designed for teams. It provides a centralized, encrypted vault where organizations can store, share, and manage credentials securely. The server exposes a JSON REST API that authenticates requests using either GPGAuth or JWT tokens, and all secrets are protected with OpenPGP end-to-end encryption, ensuring the server never has access to plaintext passwords. The platform distinguishes itself through a comprehensive role-based access control system that governs resource sharing and administrative actions. Teams can organize users into gro

Vaultwarden is a self-hosted password management server designed to store and synchronize sensitive credentials, identities, and organizational data across multiple client devices. It functions as a database-backed web application that provides an API layer for secure client-server communication, enabling users to manage personal vaults and organizational data sharing with multi-factor authentication. The project distinguishes itself through a comprehensive administrative infrastructure that provides centralized control over server configuration, user accounts, and system diagnostics via a de

A modern, open source password manager for individuals and teams.

KeeWeb is a web-based password manager and vault that allows users to open and edit encrypted databases through a browser interface. It functions as a cross-platform tool for managing password vaults using the KeePass database format. The application provides a self-hosted password vault that can be deployed as a single HTML file or via Docker. It integrates with remote storage providers using OAuth to synchronize encrypted database files across multiple devices. The system includes capabilities for secure credential generation, two-factor authentication management through time-based one-tim

This project is a password management backend designed to store and synchronize encrypted credentials across multiple devices and client applications. It serves as a secure central server that enables the management of secret vaults and password data. The system supports self-hosted secret storage, allowing users to run a private vault on their own hardware to maintain control over their data. It facilitates cross-platform credential syncing to keep passwords updated in real time across various operating systems. The backend is built with a REST-based API gateway, token-based session managem

LessPass is a stateless password manager that generates deterministic, site-specific passwords entirely on the client device. It uses a pure function to derive passwords from a master password combined with site details, producing the same output every time without storing any secrets on a server or requiring network access. This approach means passwords can be recalculated on any device from remembered inputs, with no database synchronization needed. The project distinguishes itself through its counter-based password rotation, which allows changing a site's password by incrementing a counter

Aegis is a mobile application designed to manage and store multi-factor authentication tokens. It functions as a local-first credential vault that generates time-based and counter-based one-time passwords to verify user identity across various online services. The application secures sensitive authentication data by employing authenticated symmetric encryption and hardware-backed key storage to protect credentials at rest. Access to the stored tokens is gated by system-level biometric authentication or password verification, ensuring that only authorized users can retrieve the generated secur

Linsa.io is an end-to-end encrypted cloud storage service and zero-knowledge data vault. It functions as a private content sharing platform that encrypts files and data on the client side, ensuring only the owner can access the stored content. The project employs a local-first approach, processing data updates and encryption on the local device before syncing encrypted blobs to a remote persistence layer. It uses a zero-knowledge architecture where the service provider cannot access decryption keys or view the plaintext content of stored files. The platform provides capabilities for private

This is a two-factor authentication library and open-source multi-factor authentication implementation. It provides a suite of tools for implementing security workflows that require a second layer of verification beyond standard credentials. The project implements both time-based one-time passwords and HMAC-based one-time passwords. It includes utilities for generating these codes based on shared secrets and counters, following industry standards such as RFC 6238. The library covers cryptographic primitives including Base32 secret key encoding, dynamic truncation extraction, and symmetric ke

libsignal is a cryptographic library that implements the Signal Protocol, providing the core primitives for end-to-end encrypted messaging with forward secrecy and deniable authentication. It includes the Double Ratchet algorithm for iteratively deriving fresh encryption keys per message, and the X3DH key agreement protocol for establishing shared secrets between parties asynchronously. A session state machine maintains cryptographic state across message exchanges, supporting recovery and out-of-order delivery. The library extends beyond basic messaging encryption with capabilities such as ze

This project is a comprehensive zero-knowledge security suite designed for enterprise credential management, secrets orchestration, and password management. It provides a secure, end-to-end encrypted vault that allows users to store, synchronize, and manage sensitive information, including passwords, passkeys, and infrastructure secrets, across desktop, mobile, and browser environments. The platform distinguishes itself through a strict zero-knowledge architecture where all encryption and decryption occur locally on the client, ensuring that plaintext data remains inaccessible to the server.
