Unlike many other password managers which make use of AES 256-bit encryption for keeping data safe, NordPass makes use of zero-knowledge XChaCha20 256-bit encryption across the entire password manager service. XChaCha20 encryption has several benefits over AES 256-bit including being approximately 3x faster in operational use, being more straightforward to implement and requiring less hardware support in order to operate efficiently, thus making it a great choice for a password manager service such as NordPass.
