Comparison
TokenForge vs Traditional Sessions
JWT + refresh tokens and IP binding were designed before AI agents and device-bound cryptography. See how TokenForge makes stolen sessions worthless.
| Feature | TokenForge | Traditional |
|---|---|---|
| Device proof | ECDSA P-256 signature per request (non-extractable key) | None — any device with the token is trusted |
| Stolen token impact | Replay requires the bound device key | Bearer-token access may persist until expiry |
| Trust evaluation | 7-signal trust score (device, behavior, geo, velocity) | Binary valid/invalid check |
| Adaptive security | Step-up auth triggered on anomaly detection | No adaptive response — same auth for all contexts |
| Integration path | Documented SDK quickstart | Custom implementation (days to weeks) |
| VPN / mobile support | Works regardless of IP changes | IP binding breaks on VPN, mobile, or carrier NAT |
| Session replay attacks | Blocked — each request has a unique device signature | Possible until token rotation or expiry |
| Key storage | Web Crypto API (non-extractable, hardware-backed) | localStorage / cookies (extractable via XSS) |
Attack Scenarios
Where Traditional Sessions Fail
XSS Token Theft
Traditional: A stolen bearer token may be replayed until expiry.
TokenForge: The request still requires the non-extractable private key bound to the original device.
Session Hijacking via Proxy
Traditional: A captured session cookie can be replayed from a permitted network.
TokenForge: Requests include a device-bound ECDSA signature that a proxy cannot forge without the key.
Credential Stuffing
Traditional: Automated login with stolen credentials. Short-lived tokens only limit the window.
TokenForge: Trust score drops on unknown device fingerprint, triggering step-up authentication.
Mobile IP Rotation
Traditional: Legitimate users get locked out when carrier rotates IP. Support tickets spike.
TokenForge: Device binding is IP-independent. Users stay authenticated across network changes.
When to Use TokenForge
- Your app handles sensitive data and a stolen session token means a breach, not just an inconvenience.
- Your users are on VPNs or mobile and IP binding causes false lockouts and support burden.
- You need adaptive auth that responds to risk signals without forcing re-login on every request.
- You want fast integration with 5-minute setup instead of weeks of custom session hardening.
When Traditional Works
- Low-risk internal tools where session theft has minimal impact and users are on stable networks.
- Browser support constraints where Web Crypto API is unavailable (rare as of 2026).
- Stateless microservices that only need JWT signature verification with no device context.
