Hello. Proton is almost perfect. It has perfect design and features. But one important security feature is missing.

Please, add the 2FA by phone SMS code when there is a login from new, not trusted device or country.

All other big email services have it. It's a very useful security feature.

Right now you have only 2FA by App. Also it sends the code for every new login. It's time wasting and not comfortable.

Make available 2FA by phone SMS code only when the login is suspicious, as I explained in the beginning.

I have tried this 2FA on other email sites, and it's perfect.

This 2FA is the most easy and comfortable to use.

P.S. Did you know many people don't use smartphones, only phones?
