The path to enable Face ID login in the Binance APP is: open the APP → tap the profile icon in the top left corner → Security → Biometric Authentication → turn on Face ID. Once enabled, you can quickly log in using facial recognition every time you open the Binance APP. It takes about 0.3 seconds to unlock, eliminating the need to manually enter your password. Face ID is used not only for APP login but also to confirm sensitive actions like withdrawal operations and modifying security settings, serving as a second layer of security beyond your password. All iPhones that support Face ID (iPhone X and later, including all iPhone 15/16 series) can use this feature. You can learn more about account protection measures in the Security Center on the Binance Official Website. Android users also support fingerprint login; just download the Android version via the Binance Official APP to experience it.

Explanation of Face ID Security
Technical Principles
Face ID uses the TrueDepth Camera system on the front of the iPhone, projecting over 30,000 invisible infrared dots to create a precise depth map of your face. These data are processed by the Neural Engine within the A-series chips to generate a mathematical model of your face.
Security Level
- The false acceptance rate of Face ID is 1 in 1,000,000 (one in a million), much higher than Touch ID's 1 in 50,000
- Facial data is encrypted and stored in the Secure Enclave chip of the iPhone; it is never uploaded to Apple servers or Binance servers
- Face ID cannot be spoofed by photos, videos, or 3D-printed masks
- After 5 consecutive failed Face ID recognition attempts, the device passcode will be required
Relationship with Your Binance Account Password
Face ID is a quick login method on your local device; it does not replace your Binance account password. Even if Face ID is turned off or your iPhone is lost, you can still log into your Binance account on other devices using your account password and two-factor authentication.
Detailed Steps to Enable Face ID Login
Prerequisites
- iPhone has Face ID set up: Settings → Face ID & Passcode → Confirm Face ID is enrolled
- The Binance APP is logged into your account
- The APP is updated to the latest version (v2.90 or above is recommended)
Operational Steps
Step 1: Open the Binance APP and tap the profile icon in the top left corner to enter the personal center.
Step 2: Find the "Security" option on the personal center page and tap to enter the security settings page.
Step 3: Find the "Biometric Authentication" or "Face ID / Touch ID" option on the security settings page and tap to enter.
Step 4: Turn on the "App Unlock" switch. The system will pop up a Face ID authorization request: "Binance wants to use Face ID"; tap "OK" to allow.
Step 5: The iPhone's front camera will immediately perform a Face ID verification. Look at the screen; once the verification is successful, the feature will be activated. The entire setup process takes about 15 seconds.
Optional Additional Settings
On the Biometric Authentication page, you can also choose to use Face ID in the following scenarios:
| Scenario | Recommended Setting |
|---|---|
| App Unlock | Enabled (verifies every time the APP is opened) |
| Transaction Confirmation | Enabled (verifies when placing an order) |
| Withdrawal Confirmation | Highly recommended to enable |
| Modify Security Settings | Highly recommended to enable |
| Fiat Trading | Recommended to enable |
The more scenarios enabled, the higher your account security.
User Experience of Face ID Login
Daily Unlocking Process
- Tap the Binance icon on the desktop
- The APP launches and displays the unlock interface
- Face ID automatically recognizes you (about 0.3 seconds)
- Enter the APP's main interface directly
The entire process, from tapping the icon to entering the main interface, takes about 1.2 seconds (tested on an iPhone 15 Pro/16 Pro). Compared to the manual password entry method (which usually takes 5-10 seconds), efficiency is improved by more than 5 times.
Using with a Mask
iOS 15.4 and later versions support using Face ID while wearing a mask. If you are using an iPhone 12 or newer model, you can enable the "Face ID with a Mask" feature: Settings → Face ID & Passcode → Face ID with a Mask → Turn on. Once enabled, you can complete facial recognition via the eye area even while wearing a mask, with a recognition speed of about 0.5 seconds.
Using with Glasses/Sunglasses
Regular glasses do not affect Face ID recognition. Dark sunglasses may affect the recognition accuracy because Face ID needs to detect your eye gaze direction. If you frequently wear sunglasses, you can enroll your face with sunglasses as an alternative appearance in Settings → Face ID & Passcode → Set Up an Alternate Appearance.
Face ID Related Security Suggestions
Using in Conjunction with Two-Factor Authentication
The combination of Face ID + Two-Factor Authentication (2FA) is currently the most secure protection scheme for your Binance account. It is recommended to enable both simultaneously:
- Face ID: Quick login + action confirmation
- Google Authenticator or Binance Authenticator: Generates a 6-digit dynamic verification code
- SMS Verification: Binds a phone number as a backup verification method
These three layers of protection ensure that even if one layer is breached, the account remains secure.
Periodically Update Face ID Data
If your appearance has changed significantly (e.g., growing a beard, significant weight loss, post-cosmetic surgery), Face ID may need to relearn. Path: Settings → Face ID & Passcode → Reset Face ID. Re-enrolling takes about 30 seconds, and the Binance APP's Face ID login will automatically use the new facial data afterward.
Do Not Turn Off the "Require Attention" Feature
It is recommended to keep "Require Attention for Face ID" turned on via Settings → Face ID & Passcode. This feature requires you to open your eyes and look directly at the screen to unlock, preventing others from unlocking the phone by pointing it at your face while you are asleep or unaware.
Alternatives When Face ID is Unavailable
Enter Password
After Face ID recognition fails, the APP will automatically switch to the password entry interface. You can manually enter your Binance account password to complete the login.
Consecutive Face ID Failures
If Face ID fails 5 consecutive times (possibly due to poor lighting or excessive facial obstruction), the iPhone will require the device's lock screen passcode. Entering the correct lock screen passcode will grant access to the APP.
Face ID Hardware Failure
If your iPhone's Face ID hardware fails (such as a damaged front camera), you need to disable Face ID login in the Binance APP's security settings and revert to the pure password login method. At the same time, it is recommended to take your iPhone to an Apple Store for repair. The repair cost for Face ID is approximately 1,798-3,198 CNY (depending on the iPhone model and warranty status).
Frequently Asked Questions
Which is More Secure: Face ID Login or Password Login?
Face ID is more secure. Passwords can be peeked at, leaked, or brute-forced, whereas Face ID's false acceptance rate is only one in a million, and facial data is encrypted and stored locally in the Secure Enclave, making it impossible to extract or duplicate.
Do You Still Need to Remember the Password After Enabling Face ID?
Yes. Face ID is a quick login method and does not replace the password. A password is required in the following situations: the first unlock after an iPhone restarts, after 5 consecutive Face ID failures, if the device hasn't been used for 48 hours, or when logging into Binance on a new device.
Can Someone Else's iPhone Use My Face ID to Log Into My Binance?
No. Face ID data is stored in the Secure Enclave of each individual iPhone and belongs only to the current device. Your facial data will not sync to other iPhones. Even if Binance is installed on another iPhone and logged into your account, it would require the Face ID enrolled on that specific iPhone to unlock, not your Face ID.
Can Face ID and Touch ID Be Enabled Simultaneously?
An iPhone supports only one type of biometric authentication: models with Face ID (iPhone X and later) use Face ID, while models with a Home button (iPhone 8 and earlier, iPhone SE) use Touch ID. The Binance APP will automatically detect the biometric type supported by the device and provide the corresponding option.
Will Face ID Settings Be Lost After Updating the Binance APP?
Normal updates will not cause Face ID settings to be lost. However, after a major version update (such as upgrading from v2.8x to v2.9x), you might need to re-authorize Face ID in very rare cases. Re-authorizing simply requires turning the security setting off and on once, which takes about 10 seconds.
