I actually don't have a smartphone. Unfortunately I did get a tablet, as I need it for MFA to access some websites that I need. It's quite annoying to be forced into this though. There is a push towards making this mandatory. The ideal perma-ID governments dreamed about.
Do you need the tablet? For the usual 2fa that generates a six digit code you can just install an app on your laptop. Of course it's not actually 2fa but the website doesn't know that.
