Zero-Knowledge Architecture

Military-Grade Security

Zero-knowledge architecture with end-to-end encryption. Even we can't see your passwords.

Zero-Knowledge Architecture

Your master password generates two separate keys through Argon2id:

๐Ÿ”‘

Authentication Key

Used only for login. We send the hash (SHA-256) to the server.

๐Ÿ”

Encryption Key

Never leaves your device. Used to encrypt/decrypt your data.

Encryption

๐Ÿ›ก๏ธ

AES-256-GCM

Encryption standard used by governments and militaries. Each item uses a random 12-byte IV.

๐Ÿ”’

Argon2id

Password Hashing Competition winner. Resistant to GPU and ASIC attacks.

๐Ÿ”—

TLS 1.3

All communication is protected with the latest version of TLS.

What if OneckPass is hacked?

Even in case of a breach of our servers:

  • Attackers would only see unreadable encrypted blobs
  • Your encryption key is never on our servers
  • To decrypt, they would need your master password
  • Your master password is never transmitted
