Bitwarden

Bitwarden is an open-source password manager that securely stores and auto-fills passwords, credit card information, secure notes, and identity data across all devices through end-to-end AES-256 bit encryption, zero-knowledge architecture, and salted hashing with PBKDF2 or Argon2 key derivation, enabling individuals, families, and organizations to manage credentials without trusting the service provider with access to their unencrypted data. The cross-platform availability includes browser extensions for Chrome, Firefox, Safari, Edge, Brave, and Vivaldi, native desktop applications for Windows, macOS, and Linux, mobile apps for iOS and Android, a web vault accessible from any browser, and a command-line interface for scripting and automation, with seamless synchronization across all platforms through encrypted cloud storage. The password generator creates strong random passwords with configurable length, character sets, and entropy, while the vault organization supports folders, collections, and tags for categorizing entries, with search and filtering across all stored items. The security audit features identify weak, reused, and exposed passwords by cross-referencing against known data breaches, the exposed passwords report checks against the HaveIBeenPwned database, and the password strength report evaluates overall vault security. The sharing features enable secure credential sharing between users through encrypted send links and organization vaults with granular access controls. The self-hosting option allows organizations to run the entire infrastructure on their own servers. The emergency access enables designated contacts to receive vault access after a waiting period. Designed for individuals, security professionals, IT administrators, and organizations of all sizes.
