It gets really annoying when you want to sign into $service on those machines, but you need to use a magic link. Because the you need to login into your gmail, which requires an additional 2fa (and you can’t receive sms in a building that has 6 stories but no femto cells).
Unfortunately google requires either their app or SMS. They dropped pure totp for some reason.
Awful experience.
I use TOTP with my Google Account all the time. If you have a phone registered with that Google Account it will default to the push notification system first (it might even be possible to make this no longer the default, I'm not sure), but you can always click the button to switch to alternative 2FA options.
You have to add a phone number, turn that on for 2fa.
Then you can add TOTP.
Then you can disable SMS.
SMS will still work for at least a week because fuck you.
Google plainly dropped totp wherever possible in order to confirm everyone's identity.
Totp was an open standard that didn't help them spy on anyone, and they regret releasing it bigtime.
Gmail TOTP still works fine?
