Virtual Machine Support

OnlyKey is supported on Virtual Machines in the same way as USB keyboards (USB HID).

VMware Workstation or VMware Fusion Support

  • With the VM shut down, open the .vmx file in a text editor
  • Add this line to the .vmx file and save
usb.generic.allowHID = "TRUE"
usb.generic.allowLastHID = "TRUE"
  • Restart the VM and now you will be able to connect OnlyKey to the VM

MacOS CATALINA (10.15+) requires additional security setting to access USB HID devices in VMware Fusion. Click on Apple logo on the top left of the Mac screen -> System Preferences -> Security and Privacy -> Privacy -> Input Monitoring. Select the + button and add VMware Fusion.

VirtualBox Support

  • Go to Devices -> USB
  • Select “CRYPTOTRUST ONLYKEY”

Or to have OnlyKey automatically connect to the VM whenever the VM is powered on

  • Go to Devices -> USB -> USB Settings
  • Select the add button (Green Plus)
  • Select “CRYPTOTRUST ONLYKEY”
  • Remove and reinsert OnlyKey to connect it to the VM
