Could we please get the option to ether

A) Google Auth Support for signing in
Or
b) Let us install and use the Steam Mobile app on multi devices to sign in via 2fa..

not being able to use multi-devices to be able to sign into my steam account really sucks...

at lest the Google Auth lets me use the Auth app on as many devices as I want including on my desktop and laptop.. which is the big reason why I want ether steam 2fa on google auth or let us use steam mobile app on multi devices.. so I can use my laptop and desktop to approve log-ons (I use memu play for android on desktop,, works really well)..

having to keep a single device around me all the time for simple log-ins is a huge pain in the ass...
