> AFAIK you can't plug in a Yubikey to an Android tablet, and it may not have NFC built in
Using an USB OTG adapter, it should be possible. However, even the flagship tablets of Samsung don't carry NFC, only the phones do - and even there it's a hit and miss if you have NFC.
Apple, on the other hand, doesn't have developer-accessible NFC anywhere.

This is a real shame.
