When the Bitwarden server receives the hashed password it is salted again before being stored in the database. The Bidwarden security model uses hashes and salts to protect the security of your master password and email address before transmission from your computer/device to the Bidwarden servers. Salting is the adding of random bits or cryptographic salt before hashing of passwords to protect against hacking. The hash protects messages against tampering when they are transmitted. The text (input data) can be of arbitrary length but the hash value will be of a fixed bit length. Hashing is the method of using a mathematical algorithm function to generate a numerical hash value of a string of text. Your data is always encrypted with on your local device and then sent for storage. Ultimately, none of your data is ever sent to Bitwarden’s cloud servers in an unencrypted format. When you log into your account using your master password (the decryption key) you request Bitwarden’s cloud servers to send your password to your vault for you to decrypt it. Next time you log into your vault, Bitwarden’s cloud servers become the ‘sender’ and you become the ‘receiver’. Your new password is then encrypted and stored on Bitwarden’s cloud servers. Only by using the right decryption key can the receiver decrypt the data.įor example, you save a new password in your vault. The sender encrypts the data which is then sent to the receiver in an encrypted format. No third parties can access the cryptographic keys. AES 265 encryption is used by the US government, amongst others, to protect top-secret data.ĭuring the encryption process, cryptographic keys are the only way to decrypt the information. The Bitwarden security model employs end-to-end AES 256bit encryption to safeguard your credentials before they are stored in the cloud and your vault.Įnd-to-end encryption (E2EE) can be described as a communication system that allows only the users who are communicating with each other to view and read the messages, whereas AES 265 encryption refers to a standard of cryptography.

For example, LastPass offers SMS recovery where a verification code will be sent to your phone, and Dashlane lets you use your biometrics (fingerprint) to reset your master password. Although Bitwarden’s approach is to ensure security, we think this is an area that could be improved since other password managers offer you a backup plan to reset your master password. The only option is to delete the account which will also delete the vault. However, if you forget or lose your master password there is no way to unlock or recover your vault.
The master password is not only used to unlock your vault but also to encrypt/decrypt the vault’s data. 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.
