- U2F is a standard
- The FIDO Alliance is the body that maintains the U2F standard. U2F keys can be "FIDO Certified" if they comply to the standard and have been tested.
- Yubico is a company and Yubikey is a brand. Yubikeys often support more than U2F so some Yubikeys are much more expensive than a key supporting only U2F.
- Prices start at ~$10 for a FIDO certified key
- U2F Zero is an open source project, not FIDO certified.
- I have three U2F keys of various brands and they all seem equivalent so far.
