@neauoire @zabow @ratfactor Sorry to use such words, but 2FA, which depends on a phone number or proprietary apps (only conventional app stores, like Google Play) is the biggest BS invention if it's about security.
To add a big disadvantage: I would never sign a contract to have a phone number, since ever I use prepaid cards in different countries. If I lose the sim card, I would only lose a few bugs, because I never load too much money on the card and I don't care. But making me dependent on this card, is such a no-go. If someone steals my phone, the card breaks or I lose it, 2FA will not work. No way to recover! How can this be secure?
