Passwords are often the weakest link in many computer security settings. Good, strong passwords are also difficult to remember, which can prompt users to reuse a small number of passwords on a large number of sites. But whenever passwords used on one site are exposed in a security breach, all sites where those passwords were reused are at risk of a secondary breach. Bitwarden is an open source password management solution designed to help with these issues. It generates a new, unique, random password for each site, such that passwords are never reused. These passwords are then synchronized across any number of devices using industry-standard encryption (AES-256, PBKDF2 SHA-256). Bitwarden's free tier supports sharing collections of passwords with another user (e.g. a spouse) for secure access to shared accounts. Plans that support sharing with three or more users are available for a fee. Bitwarden is available as a browser extension for Chrome, Firefox, Opera, and Vivaldi. Extensions for Microsoft Edge and Brave are in development. Bitwarden is also available for iOS and Android devices.
