Why QuantumAuth

QuantumAuth is a hardware-rooted authentication and wallet platform designed to eliminate passwords, tokens, sessions, seed phrases, and user-managed keys.

It replaces shared secrets and browser-based trust with device-bound identity, enforced by TPM hardware, post-quantum signatures, and per-request cryptographic verification.

QuantumAuth is built to remain secure even when applications, servers, or entire platforms are compromised.

The Core Problem With Existing Authentication​

Every mainstream authentication and wallet system relies on reusable secrets:

  • Passwords
  • JWTs and session cookies
  • API keys and OAuth tokens
  • SSH keys
  • Browser wallet private keys
  • Seed phrases

These secrets can be stolen, phished, leaked, replayed, or forged — especially after a server or browser compromise.

Whoever has the token wins.
This is the root flaw of modern authentication.

The QuantumAuth Model​

QuantumAuth removes shared secrets entirely and replaces them with:

  • Hardware-bound identity (TPM keys are non-exportable)
  • Post-quantum layered signatures
  • Per-request authentication (no reusable credentials)
  • Local signing and transaction submission
  • Zero trust in browsers or applications

Identity is proven cryptographically, every time, by the real device.

One-Time Device Enrollment​

  • A TPM-backed keypair is generated on the device
  • A post-quantum keypair is created as a second layer
  • Only public keys are registered with the QuantumAuth Server
  • No passwords or secrets are ever shared with applications

Even if the QuantumAuth Server is compromised, attackers gain only public keys and Argon2 hashes, which are useless for impersonation.

Per-Request Authentication (No Tokens)​

QuantumAuth authenticates every request:

  1. A fresh challenge is issued
  2. The device signs using TPM hardware
  3. A post-quantum signature is added
  4. The server verifies and consumes the challenge

There are:

  • No sessions
  • No refresh tokens
  • No bearer credentials
  • Nothing to replay or steal

Wallet Security Without Browser Wallets​

QuantumAuth wallets:

  • Use TPM-sealed keys
  • Have no seed phrases
  • Store no private keys in the browser
  • Do not allow dApps to submit transactions

dApps only request actions.
The QuantumAuth Client signs and broadcasts transactions directly, outside the browser trust boundary.

Why This Is Fundamentally More Secure​

QuantumAuth remains secure even if:

  • A backend database is breached
  • JWT secrets or session stores leak
  • A browser or extension is compromised
  • A phishing site perfectly imitates a real app

To impersonate a user, an attacker must have:

  • Physical access to the device
  • OS-level access
  • The QuantumAuth Client credentials
  • The ability to execute requests from that device

This is a radically higher bar than any existing system.

What QuantumAuth Replaces​

QuantumAuth removes the need for:

  • Passwords and MFA prompts
  • OAuth / OIDC flows
  • JWTs and session cookies
  • API keys and secret rotation
  • Browser wallets and seed phrases
  • Password managers and key files

For users, authentication becomes invisible.
For developers, authentication disappears from application code.

In One Sentence​

QuantumAuth is a hardware-rooted, post-quantum authentication and wallet system that removes passwords, tokens, browser wallets, and shared secrets by verifying every action directly from the user’s device.
