Zero-Knowledge Architecture
A security model where a service provider holds encrypted data but possesses no key to decrypt it: only the user can read their own data, including the password manager.
Zero-knowledge architecture means the service provider cannot access, read, or decrypt user data, even if compelled by law enforcement or compromised by attackers. The encryption and decryption happen entirely on the user’s device.
In a zero-knowledge password manager, the master password (or a key derived from it) never leaves the user’s device. The server stores only encrypted blobs. If the server is breached, attackers get encrypted data that’s useless without each user’s master password.
This architecture provides the strongest privacy guarantee: you don’t need to trust the provider with your data, only with storing encrypted ciphertext. TeamPassword’s zero-knowledge architecture ensures that even TeamPassword employees cannot access your team’s stored credentials.
