The Binance App supports fingerprint unlock. Once enabled, you don't need to enter a long password every time you open the app; a single touch lets you in. This feature is not only convenient but also adds a local protection layer to your account—if someone else finds your phone, they can't open the app. This article provides the complete steps to enable it on both Android and iOS. If you haven't installed the app yet, go to the Binance Official Website to download the latest version, or install the Binance Official App directly. For the full iOS process, refer to the iOS Installation Guide.
What Does Fingerprint Unlock Actually Do?
Many new users think fingerprint unlock "replaces the password," but that's not entirely true. The fingerprint unlock in the Binance App is essentially a local authorization layer:
- When opening the app, the fingerprint replaces password input, but the login token from the server is still obtained using your account password + 2FA.
- Every sensitive operation (like withdrawal or modifying security settings) may still require a Google Authenticator or email verification code.
- Fingerprint data itself is not uploaded; it is only stored in your phone's secure chip.
Therefore, fingerprint unlock is an "icing on the cake" feature, not the primary force of account security. It must still be used in conjunction with a strong password and 2FA.
Prerequisites for Enabling Fingerprint Unlock
Condition 1: The Phone Has Fingerprint Enabled
Your phone must first have at least one fingerprint enrolled in the system settings. If the phone has never recorded a fingerprint, the fingerprint toggle in the Binance App will be grayed out and unavailable.
Condition 2: The Binance App Must Be Logged In
Fingerprint unlock cannot be enabled when not logged in, because there is no account information to bind it to. Log in first using your account password + 2FA.
Condition 3: The App Version is New Enough
Older versions of the app might not have this feature. Android 2.70+ / iOS 2.70+ both support it. Update first if your version is too old.
Steps to Enable on Android
Step 1: Log into the Binance App
Open the Binance App and log in using your email/phone number + password. If you have 2FA enabled, you also need to enter the 6-digit verification code from Google Authenticator.
Step 2: Go to the "Profile" Section
Tap the "Profile" or Avatar icon on the far right of the bottom navigation bar.
Step 3: Find "Security" Settings
On the Profile page, tap "Security" or "Account & Security".
Step 4: Tap "Biometric Authentication" or "App Lock"
In the security settings page, there will be an option:
- "Biometric Login"
- Or "App Lock / APP Lock"
Tap it to open.
Step 5: Turn on the Switch
Toggle the switch for "Unlock with Fingerprint". The system will prompt a native fingerprint verification box.
Step 6: Press Fingerprint to Confirm
Place the finger you have already enrolled in the system onto the fingerprint sensor (under-display or back sensor). The switch will turn green after successful verification.
Step 7: Set the Trigger Timing
Some versions allow you to set when a fingerprint is required:
- Every time the APP is opened (strictest)
- After switching to the background for more than X minutes (e.g., 5 minutes, 15 minutes)
- Only required for specific sensitive operations (like viewing assets)
It is recommended to select "Every time the APP is opened" for the highest security.
Steps to Enable on iOS
Step 1: Log into the Binance App
Similar to Android, first log in with your account password + 2FA.
Step 2: Enter "Security" Settings
Bottom "Profile" → Avatar → Security.
Step 3: Find "Touch ID / Face ID"
Biometric recognition on iPhone is called Touch ID (older models with a Home button) or Face ID (full-screen models).
- iPhone SE / 8 and below = Touch ID
- iPhone X and later = Face ID (This article covers fingerprints; see another article for Face ID).
For Touch ID models like iPhone 7/8/SE: Find the "Touch ID Unlock" option.
Step 4: Turn on the Switch
After turning on the switch, iOS will pop up:
"'Binance' Would Like to Use Touch ID"
Press the enrolled finger on the fingerprint sensor. After successful verification, the switch will remain on.
Step 5: Test it Once
Exit the Binance App and clear it from the background, then reopen it. This time, the screen will prompt "Please verify using Touch ID" upon startup. Simply place your finger on it to enter the app.
Fingerprint Recognition Support Across Different Phone Brands
Samsung Galaxy
Under-display ultrasonic fingerprint, fast recognition speed, can recognize even with wet hands. Samsung's Knox security chip is very friendly to Binance.
Xiaomi
Under-display optical fingerprint (ultrasonic on some models), fast recognition speed, but low recognition rate with wet hands.
Huawei
Under-display optical fingerprint or back fingerprint. Good compatibility with the EMUI system.
iPhone (with Home Button)
Physical Home Button Touch ID, one of the most stable fingerprint solutions with near-zero failure rate.
OnePlus
Under-display optical fingerprint, recognition speed is top-tier among Androids.
What If Fingerprint Unlock Fails
Scenario 1: Multiple Recognition Failures
After 5 consecutive failures, the Binance App will revert to Account Password + 2FA login. This is a normal fallback mechanism.
Scenario 2: Newly Added Fingerprint Not Synced
If you enroll a new finger in the system settings, the Binance App might not recognize it. Solution: Turn off fingerprint unlock in the App's security settings and turn it on again.
Scenario 3: Fingerprint Sensor Hardware Failure
The fingerprint sensor on some older phones might be damaged or aged. First, test if the fingerprint works in other system apps. If the system can't recognize it, it's a hardware issue.
Scenario 4: Becomes Invalid After System Update
After major Android/iOS version upgrades, biometric APIs might change, causing the App to temporarily fail. Updating the Binance App to the latest version usually fixes it.
Security Boundaries of Fingerprint Unlock
What it Can Do:
- Prevent the App from being immediately opened after the phone is snatched.
- Require liveness verification every time the App is opened, preventing strangers from entering.
- Form a two-layer protection combined with the phone's lock screen.
What it Cannot Do:
- Cannot replace 2FA—critical operations like withdrawals still require Google Authenticator.
- Cannot prevent remote account theft—someone logging in from the web version doesn't need your fingerprint.
- If the phone is rooted/jailbroken, the security of the fingerprint drops significantly.
- The fingerprints of identical twins have an extremely low probability of passing (but it's much better than Face ID).
Security Recommendations for Combined Use
- Fingerprint + Strong Password + 2FA is the most robust combination.
- Enroll at least 2 different fingers to prevent being locked out if your primary finger is injured.
- Enable "App Lock" alongside fingerprint for double insurance.
- Change your password every 3 months; even if your fingerprint is compromised, the password protects the account.
- If you lose your phone, immediately log into the web version, go to the Security Center, and unbind biometric recognition for that device.
Frequently Asked Questions
Q: Can a fingerprint replace 2FA?
A: No. A fingerprint is only a local App unlock layer. 2FA is account-level security verification. Operations like withdrawals still require the 6-digit code from Google Authenticator.
Q: Will a child mistakenly open the App using the same phone?
A: As long as their fingerprints are not enrolled in the phone system, they cannot open it. It is recommended for children to use an independent kids' account or not to share phones.
Q: If my phone is stolen, is the fingerprint unlock still safe?
A: Safe in the short term. The thief cannot get in without your fingerprint. However, it is recommended to immediately freeze the account via the web version and log out the device remotely.
Q: Will turning off fingerprint unlock affect my account?
A: Not at all. Turning it off simply returns you to the password login mode. The account, assets, and settings remain untouched.
Q: Why can't I find the fingerprint unlock option on my Android phone?
A: It might be because the system hasn't enabled fingerprint, or the App version is too old. First, enroll your fingerprint in the system settings, then update the Binance App to the latest version.
