Worth noting that you can install the Authy iPad app on ARM Macs (unsure about Intel, but I'm skeptical)

but seriously, what a terrible app, another great reason to get off that platform

This literally saved me some years ago when my phone gave up and I was travelling.

Plus since everything uses 2factor nowadays, it's really annoying if your phone dies or isn't otherwise right next to you

The desktop app solved this problem for me
