Yubikey5C and Yubikey5C+NFC not working on my Nvidia Shield. I have to sign into my google account. I type my password in and the second factor is the Yubikey. I put in the yubikey 5 the led lights and I put my finger on the button of the yubikey. I tried the 5C as well as the 5C with NFC.

Ok, so after I signed my google account t over to 2fa, (password then Yubikey) my Nvidia Shield (Android TV box) wanted me to sign back in to my google account. (on the box, connected to the tv) I put in my google account username and password. Then for the 2fa, it asked for my Yubikey. I inserted my Yubikey into the USB port on the Shield, got the (lit) led and put my finger on the button. Nothing!! Just the little flash type thingy showing the way to insert the yubikey into the USB port. But, again, when I do that, nothing happens. Well, the led comes on and I push the button, as this is how it works on everything else, but it does not recognize that I am inserting the key. Any experience with 2fa on the Nvidia Shield? I have tried my yubikey5NFC and my yubikey5 C. Or some kind of workaround? Thanks. Just had surgery, I am home bound, stuck at home.....Help me fix this. I need my video fix!!!! Thanks to all.

From memory, it allows you to use a backup method in place of the key - one of those should be to send you a SMS with a token, I tend to use that when on a device that doesn't support U2F.

But it's been a while, I don't really remember logging into the shield it's been so long 😂

Yeah, use one of your one-time use back up codes. You don't need to do it often.

Only way I found that works was either using a backup code or adding a google authenticator 2FA to your account in addition to the yubikey. The Shield straight up doesn't support the hardware via usb, and there's no NFC at all.

There is also an app called Duo that you can connect with Yubikey. Instead of pressing Yubikey you type "push" and it will bring the app on your phone.
