Fingerprint parameter reference
Configure these in Create / edit profile. Verify with FingerprintJS and BrowserLeaks.
Short list
See Verified fingerprint overrides for a compact checklist.
Identity & network
| Field | Effect | Tip |

| CPU cores | hardwareConcurrency | Match UA tier |
| Memory | deviceMemory | Consistent with UA |
| Device name / MAC | Device identifiers | Unique per profile |
Graphics & audio
| Field | Effect | Tip |
|---|---|---|

Verify & debug
- Launch profile → BrowserLeaks / FingerprintJS.
- Check IP, timezone, language, WebRTC alignment.
- If flagged: tune UA, Canvas/WebGL, proxy—Browser fingerprint FAQ.
- API:
POST /api/randomizeFingerprint—Update fingerprint.
