Most 2FA can be done without a phone, and you can also use offline 2FA keys, not necessarily a text message.

You can also set up a phone number to accept texts from a laptop.

I can do whatever on my bank by just calling. It would be a bit weird to never be able to pitch in on meals with a $ transfer app, but I suppose when you run 2 tech companies you're probably paying most of the time, or you just take a note and transfer it later.

Do you call via landline? I don’t know anyone who even still has one.
