Turning on 2FA and being protected aren't the same thing.
If your second factor is an SMS code, your account security now depends partly on your phone number.Phone numbers can be taken over through SIM-swapping, where someone convinces a carrier to move your number to their SIM.Your password never needs to be cracked. Your texts just start arriving on someone else's phone.
An authenticator app (Google Authenticator or Binance's own) is a real step up. The codes are generated on your device and don't travel over the phone network.
The strongest option is a passkey or hardware security key. Those are tied to the real Binance domain, so even a convincing fake login page can't get them to work. A code can be typed into a fake page. A passkey can't.
My ranking, weakest to strongest:
SMS → authenticator app → passkey / security key
One more thing people skip: when you set up an authenticator, you're shown a backup key. Write it down and keep it offline. It's what saves you if you lose or change your phone.
Path: Profile → Account → Security.
Visual suggestion: A simple three-step staircase graphic: SMS at the bottom, authenticator in the middle, passkey/security key at the top. Next to each step, one line on what an attacker needs to beat it. Plain background, no stock lock icons.
Which 2FA method are you using right now? No judgment, just curious how many people are still on SMS.
