You don't have to use your phone. In theory you may also use a Yubikey

I had a yubikey. It died after a few months of simply lying on the shelf behind me. No idea why, but havent exactly been a fan after that.

Did you get it replaced? Seems like it should have still been under warranty after only a few months.
