Devices
In order to prevent abuse of the Baymard platform, users have a limited number of devices (2 for most plans) that can be signed in at a given time. If you have 2 registered devices and sign into Baymard on a third device, you will need to confirm you want to register a new device and replace an already-registered one.
When a device is registered, it sets a cookie in the associated browser. If you clear that browser’s cookies for baymard.com, you will need to register a new device again the next time you sign in.
