Welcome to the U2F Garden!
The goal of the U2F Garden is to provide a guide on the many and varied U2F tokens and keys out there in the world. There’s a lot of them out there and I wanted to make sure that there was a good guide on what keys support what features.
Where’d this all start?
This started when I wanted to make a small adjustment to my typical SSH configuration. Normally, I’d use the PKCS11 features in my Yubikey to support this stuff. That’s great, until you realize that a Yubikey is… Expensive. And there’s other USB PKCS11 tokens out there. And then OpenSSH went ahead and implemented a feature I’d wanted for some time: U2F support!
What’s U2F support give me? A bunch of stuff, actually. It means I could feasibly have a central authority for more of my SSH keys, including not having to haul around secret keys and maintain a trusted keys file all over the place. For someone like me, that’s a huge boon.
