2FA for some regions in IOS app

There seems to be 2FA support for Germany and Canada now. I wonder what 2FA mechanism is used. I hope we can choose and not go for things like sms which are prone to sim swap attacks.

I wonder how i can use the 2FA. Haven‘t found anything yet. I‘m located in Germany.

I’m in the UK and just looked at my IOS App updates and there is a new version 1.7.6 which mentions Support two-factor authentication for Germany and Canada Regions

They use email or sms. Hopefully add to other geos soon.

Come on USA 2fa.

So glad 2fa has been delivered in the USA
