Describe your hardware so each captured fingerprint is labelled with known ground truth. A capture attaches to a device; an environment (an OS install, optionally a nested VM) belongs to a device; a browser profile belongs to an environment.
An OS install on a device. A VM nests inside its host (up to 4 levels deep).
A browser (and optional profile) running inside an environment.
Capture a fingerprint on a device that can't sign in (a games console, smart display, or kiosk). Pick the target device (and optionally its environment / browser profile), generate a one-time code, then on that device open capture.html and enter the code. The capture lands here, on your account. Each code is good for one capture and expires after 15 minutes.
Write this down now — you won't be able to see it again.
Fingerprints you've submitted, newest first. Expand a capture to see its raw JSON, or open it in the full data-point table.
