Lock your passwords and private information with end-to-end AES-256 bit encryption, salted hashing, and PBKDF2 SHA-256.

You can use it in unlimited devices with syncing.

What are the best Bitwarden features?īitwarden is a solid free password manager for several reasons: There's the option to upgrade to a premium account ($10 annually), which adds advanced 2FA options, the Bitwarden Authenticator (TOTP), encrypted file attachments and emergency access. Is Bitwarden free?īitwarden offers a free account with unlimited storage of logins, access to your vault on any device (PC or mobile), a secure password generator, and a few other features. Bitwarden servers store only the encrypted data.

Bitwarden encrypts your data on your local device before sending it to its cloud servers for storing. It uses 256-bit AES encryption to lock your vault and a master password is required to decrypt the data. Is Bitwarden trustworthy?īitwarden is safe and open-source. When you reuse the same passwords everywhere hackers can easily access your email, bank, and other important accounts. Security breaches occur and your passwords are stolen. The websites and apps that you use are under attack every day. Instead, changing a password just requires decrypting the master key with the old password-derived key, and re-encrypting it with the new one.Secure cloud syncing lets you access your sensitive information from anywhere on any device. The password-derived key is not itself used to encrypt/decrypt the data, because then if the user changed their password it would be necessary to re-encrypt everything. More advanced schemes involving public key cryptography are sometimes used to enable sharing select data with other users, without giving them access to your master key or any data you didn't want to share.

A simple implementation is to encrypt the master key with the password-derived key this encrypted master key can only be decrypted on the client (the server never sees the password-derived key). This encrypted master key, along with the encrypted data, is transmitted to the user upon successful authentication. Typically the master key is stored on the server, alongside the user's data, in encrypted form. The other one is used as a 'password-derived key' that is the first step to obtaining the master key for decrypting the database. One hash is used to generate a login token (used like a password) which is sent to the server (where it gets additional hashing, and possibly also requires stuff like MFA). The user password is pre-hashed with a slow password hashing function on the client side, twice, using different algorithms and/or salts.
