Definition
Bitwarden is an open-source password manager that lets individuals and teams securely generate, store, and share encrypted credentials across browsers and devices.
Overview
Bitwarden encrypts vault data end-to-end using AES-256 encryption before it ever leaves the user's device, so even Bitwarden's own servers only ever see ciphertext — a zero-knowledge architecture common among reputable password managers. It's available as browser extensions, desktop and mobile apps, and a command-line tool, and it supports two-factor authentication for securing the vault itself. Unlike many closed-source competitors, Bitwarden's client and server code is open source, and organizations can self-host the entire service if they want full control over where vault data lives, in addition to Bitwarden's official cloud offering. For teams, it supports organization-level vaults with granular sharing permissions, which is useful alongside secrets-management tools like Vault or identity platforms like Auth0 and Keycloak in a broader security stack.
