Yes, but that's a highly technical solution. I've been trying to get my girlfriend to use Authy for 6 months now, and the solution we landed on is that my Authy app has all of her 2FA codes, and she just calls me if she needs one.
To you and me 2FA doesn't seem that complicated. But to less technical people it's just overwhelming and they don't want to bother with the learning curve.
What learning curve? Setting up the account in the first place? Sure, that’s a tad complicated, but I really don’t understand why your girlfriend finds it easier to call you when she just has to open the app and the code is simply there.
