Fast ID Online or FIDO version 2.0
- All FIDO specs including the most recent version 2.0.
- Replacement for FIDO U2F and FIDO UAF of version 1.0.
- One reason to like FIDO is that there are many different authentication methods that you can do. There are keys like YubiKey and Solokey and there is also Windows Hello where you can just type in a PIN. Quote from Authenticate 2021
