Master Passwordīitwarden requires you to use a master password to access your encrypted vault. Only you can unlock and decrypt the passwords stored in your vault using your master password. Nobody from Bitwarden (or any other third-party) ever has access to your unencrypted data. Only encrypted data is stored in your vault and on Bitwarden’s cloud-based servers. Like most password managers, Bitwarden operates a zero-knowledge model where all your passwords are encrypted on your device.

As a result, the security model is kept up-to-date with industry standards. More importantly, Bitwarden is also officially audited by third-party security firms to evaluate the app’s cryptographic design (the practice and study of techniques for secure communication by transforming messages in ways that are hard to decipher). Being open-source is regarded as one of the most important features of Bitwarden because it’s peer-reviewed, meaning it is open to a large base of inspectors who can quickly detect and fix any security flaws.

This allows transparency about how the password manager works and how user data is handled. Bitwarden made the source code 100% available, under an open-source GPLv3 license. The source code for Bitwarden is hosted on the popular GitHub platform and anyone interested in the under-the-hood mechanics can download the code and investigate it further.
