Is this any good? I'd love to buy one but the USB looks too old-fashioned and doesn't have a case supporting it, possibility of it to break easily is also a thing to be taken into consideration before buying it.
I think it's the best alternative but yeah I admit it looks like a prototype from 2000. There is a tutorial if I remember so you can make your own from scratch.
There are other USBs more "swag" for example FIDO U2F Security Key from Yubico https://www.yubico.com/
