A major advantage for iOS users is the seamless Face ID / Touch ID experience. The Binance APP supports fortifying security with biometrics on three levels. This article explains each one clearly. Download links: Binance official website, mobile Binance official APP. If you haven't installed the iOS app, see the iOS installation guide.
1. Three Areas Where Biometrics Can Be Enabled
| Location | Function | Recommendation |
|---|---|---|
| APP Startup Lock | Verification required on every open | Enable |
| Login Confirmation | Bypass entering 2FA | Enable (Trusted devices only) |
| Withdrawal / Transfer Confirmation | Alternative to 2FA verification | Depends on scenario |
2. APP Startup Lock
Settings → Security → App Lock → Face ID. Once enabled, you must verify your identity every time you switch back to the APP.
Applicable scenarios:
- Preventing transaction history from being snooped on when lending your phone
- Protecting account privacy when sharing a tablet
- Preventing shoulder surfing when opening the APP in public places
When not to enable: You have exclusive use of the device and a strong lock-screen password.
3. Login Confirmation
On trusted devices, Binance supports "Fast Login," allowing you to bypass 2FA after entering your password by using Face ID confirmation instead. The prerequisite is that the device has already been added to your trusted list.
Setup: Settings → Security → Trusted Devices → Enable Face ID Login.
Note
This should only be enabled on your personal devices. When borrowing someone else's iPhone, you should always go through the full 2FA process.
4. Withdrawal / Transfer Confirmation
When withdrawing funds, in addition to the 2FA verification code, you can add a layer of Face ID confirmation. Settings → Security → Withdrawal Confirmation → Enable Face ID Secondary Confirmation.
Advantages
Even if an attacker gets your 2FA code (via phishing or social engineering), they cannot complete the withdrawal without your face. This is the closest biological defense to a "hardware security key."
Limitations
Face ID data is stored in the Secure Enclave and is theoretically uncopiable. However, under coercion scenarios (e.g., kidnapping), an attacker can force you to face your phone. Therefore, for high-value accounts, it is still recommended to add a hardware security key.
5. Pairing with Hardware Security Keys
The strongest combination:
- APP Startup Lock (Face ID)
- Login without 2FA (Face ID)
- Withdrawals using YubiKey (USB-C plugged directly into iPhone 15 Pro or newer)
The private key of a YubiKey never leaves the hardware; an attacker cannot withdraw funds even if they see all your verification codes.
6. Backup Plan for Face ID Failures
In case Face ID fails to recognize you (wearing a mask, bright light, device malfunction), Binance offers:
- Entering your Apple ID password as a fallback
- Or reverting to the Password + 2FA process
When setting this up, ensure your password and 2FA are still valid. You shouldn't be locked out when biometric authentication fails.
7. Privacy Concerns Regarding Biometrics
iOS Face ID / Touch ID data:
- Is stored in the Secure Enclave hardware chip
- Is not uploaded to Apple's iCloud
- Is not shared with Binance servers
- Binance only receives a "recognition passed/failed" signal, not the raw data
Therefore, enabling it will not let Binance "acquire your face." It is safe in terms of privacy.
FAQ
Q1: What if Face ID doesn't recognize me while wearing a mask? iPhone 12+ supports Face ID with a mask. Settings → Face ID → Enable "Face ID with a Mask." Alternatively, switch to Touch ID (if your model has it).
Q2: Can Face ID recognize twins? Apple officially states the Face ID false acceptance rate is 1 in 1,000,000, but twins might still trigger false positives. For high-value accounts, it is recommended to combine it with an Apple ID password or YubiKey.
Q3: Do I need to reset Face ID after changing to a new iPhone? You don't need to reset Face ID for your Binance account—Binance only remembers that you "previously enabled Face ID verification." When you launch the APP for the first time on a new device, it will ask you to re-enable it once.
Q4: What if my iPad doesn't have Face ID? All iPads have Touch ID (or Face ID for Pro series). Both have the exact same effect.
