I bought a YubiKey for U2F (https://www.yubico.com/product/security-key-by-yubico)
I followed the below tutorial to generate a SSH Key that supports a U2F key:
Unfortunately, when I tried to add the public SSH Key to my Bitbucket account, I get a "That SSH key is invalid." message.
I know the website supports U2F as a second factor for login. Are there plans to support U2F SSH keys?
