That was my point. Using a mobile phone as a second factor seems more like an inconvenience.

Other sibling mentioned IMEI pinning, but I assume the emulator can spoof IMEI.

I am all for a separate physical device, just not a phone.

A phone is just a computer, just like any other device. What do you have specifically against it? You can just keep it turned off except when you need to use it for 2FA.
