2FA Comparison Table
Binance offers several second factors, and they're not equally safe. Here they are in one table, weighed on phishing resistance, SIM-swap resistance and how hard recovery is, so you can pick the right lock. These are plain judgements — the exact methods and screens Binance supports are whatever its official pages show at the time.
| Method | Security level | Phishing resistance | SIM-swap resistance | Switch device / recover | Who it suits |
|---|---|---|---|---|---|
| SMS code | Weak | Weak | Weak | Painful when the number changes | A bare-minimum fallback when nothing else is possible — keep it as backup only |
| Authenticator app Google Authenticator, Authy, etc. | Solid | Medium | Strong | Needs migration or a recovery code | The default choice for most people |
| Security key (hardware) YubiKey and similar | Strongest | Strong | Strong | Keep a spare key on hand | Larger holdings; want phishing resistance built into the mechanism |
| Passkey / biometrics | Strongest | Strong | Strong | Tied to a device; keep a backup method | Anyone who wants strong yet convenient, on a supported device |
In one lineIf you can use an authenticator app, don't rely on SMS alone; for a level up, add a security key or passkey. SMS isn't forbidden — just never let it be your only second factor.
About this tableThis is a qualitative comparison of each method — no invented numbers or made-up scores. "SIM-swap resistance" is about whether an attacker who re-issues your phone number can slip past: SMS gets bypassed, while authenticators and security keys don't lean on your number, so they hold up better. For which methods Binance actually supports and how to turn them on, go by its official pages.
