That extra step is especially important for email, banking, and health portals, where a takeover can expose private information fast. This article explains how 2FA works behind the scenes, where it can still go wrong (like SIM-swap attacks or lost devices), and how to pick the right method and set it up in a way that’s secure without being a daily hassle.
