Stevedcc/TokenSwap: A Yubikey-Enhanced Password Manager with Token Swap Features to Safeguard Against Command Line History and AI Vulnerabilities

Unlocking Secure AI Operations with Tswap

In today’s digital landscape, protecting sensitive information is paramount, especially as AI agents increasingly handle critical secrets. Tswap offers a hardware-backed secret management solution designed specifically for AI environments. Here’s how it elevates security:

  • Seamless Token Management: Tswap allows AI agents to utilize passwords without ever revealing them, employing {{tokens}} that replace values at runtime. This means plaintext remains obscured from agent interaction, enhancing confidentiality.

  • Redundant YubiKey Integration: Two YubiKeys are enrolled just once, enabling users to unlock their vaults independently via XOR key reconstruction. One can be stored safely while the other is in use, eliminating the need for re-enrollment if lost.

  • Privilege Boundary Enforcement: Tswap’s sudo boundary ensures that commands using secret values bypass the need for elevated privileges, while commands exposing secrets do not.
