Does anyone use a Yubikey for personal rather than business/employment situations? Would a Yubikey ring make any sense for personal use (for example, you have Yubikey ring that connects via NFC with your device (phone, computer) and is require for auth'ing financial transactions?

I use a Feitian epass for my personal accounts (it seems like yubikeys are USB or NFC whereas I wanted a single key that would do both). It fits on my keyring (smaller than my house key) and claims to be waterproof. I wish I could use something like that for banking - it's much more convenient than the little card readers some banks use, and frankly I have more faith in its security. A ring form factor would be nice, but I don't think NFC on PCs is ubiquitous enough yet.

That is sort of the idea. It's a relatively cheap authenticator that can be bought to provide 2FA for added security for your services. You can integrate it with Gmail, Mac Logins, etc.

Yes, I'm interested in general adoption and whether general populous would adopt such a 2nd-auth if presented as a fashion item (i.e. make the authenticator more accessible).

In the UK Barclays and NatWest (maybe others) offer a card reader for 2FA for banking transactions, I assume based on something like HOTP.
