2FA in 2020 and Beyond
summary
Data show tradeoffs: SMS is easy to onboard but vulnerable to SS7 and SIM‑swap; Google finds SMS blocks 100% of automated bots, 96% of bulk phishing and 76% of targeted attacks. TOTP (soft tokens) is offline and standardized but leaks if the shared secret is exposed and many users mistype expiring codes. Push and WebAuthn/U2F are fastest and more phishing‑resistant (push adds ~13 minutes saved yearly, U2F ~18) but need apps or $50 hardware keys and better onboarding. Support multiple methods and prioritize clear setup to raise adoption.
