Why Carbon Vault

Your passwords belong to you.

Most password managers can technically access your data. They hold the keys to decrypt your vault if needed. With Carbon Vault, true zero-knowledge means your master password never leaves your device—we literally cannot see your passwords.

What others do

  • Can technically decrypt your vault
  • Send passwords to cloud for AI features
  • Require account recovery access
  • Store encryption keys on their servers

What we do

  • True zero-knowledge architecture
  • AI runs 100% on your device
  • Keys derived client-side only
  • We can never access your data
