Passkey, in plain terms, lets you log in securely without memorizing a password. Just use your fingerprint, face, or device PIN, and you're in — easy and secure. Binance already supports Passkey, but many people don't know how to set it up. Today I'll walk you through it step by step. The whole process is actually quite simple. Make sure you have an account on the Binance official website. Setting up via the Binance official app is the most convenient. Apple users can check the iOS installation guide.
What Exactly Is Passkey
Before we get into the setup, let me briefly explain what Passkey is.
Traditional login uses "username + password." The password is stored on the server (encrypted, of course), and it's transmitted every time you log in. This creates several issues: your password could be stolen by phishing sites, hackers could extract it from a breached database, you might set a weak password, or you might reuse the same password across multiple sites...
Passkey uses a completely different technology. It generates a key pair on your device — the private key stays in your device (like in your phone's secure chip), and the public key is sent to Binance. When you log in, your device signs a "proof" with the private key, and Binance verifies it with the public key. No password is transmitted, and there's no possibility of "password theft."
All you need to do is press your fingerprint or glance at your phone (for face recognition).
Benefits of Passkey
- Anti-phishing: Passkey is bound to the website's domain, so fake websites can't trigger your Passkey
- Leak-proof: Only the public key is on the server — even if hackers steal it, it's useless
- Super convenient: Just press your fingerprint to log in — no passwords to remember, no codes to enter
- Cross-device sync: If you're in the Apple or Google ecosystem, Passkey can sync to your other devices via iCloud or your Google account
Before You Start
Confirm you meet these requirements:
Device Requirements
- iPhone: iOS 16 or later
- Android: Android 9 or later (Android 14+ recommended for the best experience)
- Computer: Windows 10/11 (requires Windows Hello), macOS Ventura or later
- Browser: Chrome 109+, Safari 16+, Edge 109+
Account Requirements
- Identity verification (KYC) completed
- At least one two-factor authentication method enabled (e.g., Google Authenticator)
- Account in good standing — not frozen or restricted
Setting Up Passkey on Mobile (Recommended)
Mobile setup is the simplest, and I recommend this approach.
Step 1: Go to Security Settings
- Open the Binance app
- Tap your profile icon in the bottom-right to enter "Profile"
- Find "Security" or "Security Settings"
- Look for the "Passkey" option in the list
Step 2: Add a Passkey
- Tap "Add Passkey" or "Create Passkey"
- The system will ask you to verify your identity — this may require your password, Google Authenticator code, or face recognition
- After verification, your phone will display a system-level Passkey creation prompt
Step 3: Complete Biometric Verification
- iPhone users: A Face ID or Touch ID confirmation dialog will appear — just verify
- Android users: A fingerprint or facial recognition dialog will appear
Once verified, your Passkey is created! The entire process takes less than a minute.
Step 4: Test It Out
After creation, I recommend logging out and trying to log back in with Passkey. The login screen will have a "Log in with Passkey" option. Tap it, verify your fingerprint or face, and you're in.
Setting Up Passkey on Desktop
If you prefer working on a computer, you can set it up on the web.
- Open the Binance official website in your browser
- Log in to your account
- Click your avatar in the top-right → "Security Settings"
- Find "Passkey" and click "Manage"
- Click "Add Passkey"
- Complete security verification
- The browser will display a system dialog
On Windows, it will invoke Windows Hello, where you can use your fingerprint, face, or PIN to create a Passkey. On Mac, it will use Touch ID or your system password.
You can also select "Use another device" and scan a QR code with your phone to create the Passkey, which will then be stored on your phone.
Managing Your Passkeys
View Created Passkeys
On the Passkey page in Security Settings, you can see all your created Passkeys, including:
- Creation time
- Device name
- Last used time
Delete a Passkey
If you've changed phones or want to remove a Passkey, find it in the list and tap "Delete." The system will ask you to verify your identity again before deletion.
You Can Create Multiple Passkeys
I recommend creating Passkeys on multiple devices. That way, even if one device is lost, you can still log in from another. For example, create one on your phone, one on your tablet, and one on your computer.
Passkey and Other Verification Methods
Can Passkey Replace Google Authenticator?
Currently, Passkey primarily serves as an alternative login method rather than a full replacement for all two-factor authentication. You can use Passkey to replace the "password + SMS/Google code" login flow, but high-risk operations like withdrawals may still require additional verification.
Recommended Security Combination
My recommendation: Passkey + Google Authenticator + Email verification. With all three enabled, your security level is very high.
- Passkey handles daily logins — quick and convenient
- Google Authenticator provides secondary confirmation for high-risk operations like withdrawals
- Email verification serves as the final line of defense
Security Reminders
Important security considerations when using Passkey:
- Passkey is stored in your device's secure chip, so your device's own security is critical — always set up a lock screen password/fingerprint/face recognition
- If you sync Passkey via iCloud, make sure your Apple ID has two-step verification enabled with a strong password
- Before switching phones, confirm your Passkey has synced to the cloud, or create a new one on the new phone
- Don't create Passkeys on untrusted devices
- Even with Passkey set up, don't remove Google Authenticator — they complement each other
- Create Passkeys on at least two devices to avoid a single point of failure
Troubleshooting
Passkey Creation Keeps Failing
Check these first:
- Is the app on the latest version
- Does your phone meet the minimum system requirements
- Is a VPN causing network issues
- Is your phone's biometric function working properly
If everything checks out and it still fails, try restarting the app or switching network environments.
"Cannot Verify" Error When Logging In with Passkey
Possible causes:
- You're trying to log in on a device where no Passkey has been created
- You recently reset your phone's biometric data (e.g., re-enrolled fingerprints)
- Your device's secure chip has an issue
Solution: Log in using the traditional method (password + verification code), delete the old Passkey, and create a new one.
FAQ
If my phone is lost, is my Passkey gone forever?
Not at all. First, if you're using an Apple device, Passkey syncs to your other Apple devices via iCloud Keychain. Android works similarly through your Google account. Second, you still have password + Google Authenticator as a backup login method. So if your phone is lost, you can still log in from another device. Just remember to create a new Passkey on the new device as soon as possible.
Can I still use password login after setting up Passkey?
Yes. Passkey exists as an additional login option — it doesn't disable your original password login. You can choose to log in with Passkey or with the traditional password method. Both coexist.
Could someone use Passkey to log in to my Binance if they get my phone?
Theoretically, if they can pass your phone's biometric verification (fingerprint or face), then yes. That's why your phone's own security is crucial. Don't enroll other people's fingerprints on your phone, and never disable the lock screen. In practice, the difficulty of faking fingerprints or facial recognition is far greater than stealing a password.
Can I set up Passkey for each of my multiple Binance accounts?
Yes, each account gets its own independent Passkey. You can store multiple Passkeys for different accounts on the same device, and the system will let you choose which one to use when logging in.
What's the difference between Passkey and a hardware key (YubiKey)?
Both use similar underlying technology (FIDO2 standard), but the form factor is different. Passkey is stored in your phone or computer and uses biometric verification. A hardware key is a separate USB device that must be physically inserted. Hardware keys are theoretically slightly more secure (since the private key is in standalone hardware), but Passkey is far more convenient. For most people, Passkey is already secure enough.
