Vault Data

All vault data is encrypted by Bitwarden before being stored anywhere. To learn how, see Encryption.

Vault data can only be decrypted using a key derived from your master password. Bitwarden is a zero knowledge encryption solution, meaning you are the only party with access to your key and the ability to decrypt the vault data. Listed below are examples of the data that is encrypted, as well as download links demonstrating the encrypted data.
