I was not aware of that and it does sound like a solution. However I'd love to have a hardware device that I don't need an app to use. To load the keys and configure it I have no problem with, but to actually read the TOTP it would be great if I could just click a button and read a display instead of having to use extra infrastructure. Kind of like my 2FA token for my bank, which just requires me to push a button and that's it. Thanks for the tip though.
