Anyone use hardware MFC authentication keys, and have opinions about them?
Are they a good solution?
I saw a video about YubiKey and looked it up on Wikipedia. Seems like a useful thing, but there are FOSS community concerns about it being closed-source.
The page also mentions NitroKey which appears to be a FOSS/Open Hardware alternative that supports (most of?) the same protocols.
Which?
Neither?
Comments..?
