Are there limitations to U2F keys?

Yes, there are a few limitations to U2F keys.

1. You must be using a device with a USB port, and the USB port must not be disabled (some kiosks and computer labs disable USB ports for security reasons).
2. You must be using a supported browser. Google Chrome and Opera support U2F natively. While Firefox does not natively support U2F, there are extensions that may add U2F functionality.
