I have never used my Yubikey with my phone for any application, I don't even know if it works, and I see no reason why I would start. I almost never use Twitter

I have never used my Yubikey with my phone for any application, I don't even know if it works, and I see no reason why I would start. I almost never use Twitter on my phone and if I switched Twitter to my Yubikey, I would never use it on my phone.
