How registration works
The first time you access the platform on a new device, it's automatically registered to the appropriate slot. You'll see a brief verification screen, then you're in.
Viewing your registered devices
Go to My Devices from the sidebar (or your account page) to see all registered devices with their names and registration dates.
Device registration uses your browser's fingerprint, which means switching browsers on the same machine is generally fine — it's recognized as the same device.
