Keeping your data secure

As your password manager and credential security provider, Bitwarden utilizes trusted security measures and encryption methods to protect user data.

Zero-knowledge, end-to-end encryption

Bitwarden uses end-to-end encryption for all vault data, which only your master password can decrypt. With a zero-knowledge architecture, Bitwarden does not have the ability to read any encrypted data in your vault.

Multifactor encryption

Multifactor encryption is an additional layer of encryption that protects your stored information. This makes it practically impossible for a bad actor to break into your vault, even if they were able to gain access to your encrypted vault data.

Self-hosting options

Choose to deploy and manage Bitwarden on-premises in your private network or infrastructure with self-hosting options. Self-hosting allows customers to have more detailed control over their stored information.

Bitwarden takes extreme measures to ensure that its websites, applications, and cloud servers are secure. Bitwarden uses Microsoft Azure managed services to manage server infrastructure and security, rather than doing so directly.

Learn more >

Bitwarden regularly conducts comprehensive third-party security audits with notable security firms. These annual audits include source code assessments and penetration testing across Bitwarden IPs, servers, and web applications.

Bitwarden processes and stores all vault data securely in the Microsoft Azure Cloud in the US or EU using services that are managed by the team at Microsoft. Since Bitwarden only uses service offerings provided by Azure, there is no server infrastructure to manage and maintain. All uptime, scalability, security updates, and guarantees are backed by Microsoft and their cloud infrastructure. Review the Microsoft Azure Compliance Offerings documentation for more detail.

PBKDF2 SHA-256 is used to derive the encryption key from your master password, however you may choose Argon2 as an alternative. Bitwarden salts and hashes your master password with your email address locally, before transmission to our servers. Once a Bitwarden server receives the hashed password, it is salted again with a cryptographically secure random value, hashed again, and stored in our database.

Bitwarden always encrypts and/or hashes your data on your local device before anything is sent to cloud servers for storage. Bitwarden servers are only used for storing encrypted data. For more information, see Storage.

Bitwarden uses AES-CBC 256-bit encryption for your vault data, and PBKDF2 SHA-256 or Argon2 to derive your encryption key.

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

Data that is stored on your computer/device is encrypted and only decrypted when you unlock your vault. Decrypted data is stored in memory only and is never written to persistent storage.
