Why QuantumAuth?

QuantumAuth is an open-source, hardware-anchored authentication layer that eliminates passwords, bearer tokens, refresh tokens, and user-managed keys.
It binds identity to TPM hardware, a post-quantum signature layer, and a device-local daemon, ensuring that no third-party platform ever stores credentials that can be reused or stolen.

QuantumAuth delivers:

  • No single point of failure
  • Credential-less authentication for third-party platforms
  • Hardware-bound identity (TPM keys cannot be exported)
  • Post-quantum security through additional signature layers
  • Attack resistance even if the QuantumAuth server or a third-party backend is fully compromised

2. Transparent Authentication Workflow​

Guarantees​

  • No single point of failure
  • No credentials stored on third-party systems
  • TPM private keys cannot be exported
  • PQ signatures add a post-quantum layer

To compromise one account, an attacker must have:

  • Physical access to the device
  • OS/device credentials
  • The qa-client password
  • Ability to send requests from that device

3. Comparison With Classic Authentication​

JWT Authentication​

Session-Based Authentication​

SSH Key Authentication​

4. Why QuantumAuth is Different​

Traditional authentication mechanisms rely on shared secrets, tokens, or user-managed private keys.
QuantumAuth replaces all of these with:

✔ Hardware-bound identity​

TPM keys never leave the device.

✔ Post-quantum layered signatures​

Break one layer, still can't impersonate.

✔ Zero credentials stored on third-party platforms​

Nothing to steal, dump, or leak.

✔ Server compromise is not enough​

Public keys + Argon2 hashes are useless without the real device.

QuantumAuth shifts authentication from:

“Whoever has the token wins”
to
“Only the legitimate device + user can ever produce a valid signature.”
