OKX now supports FIDO (Fast Identity Online) passkeys for two-factor authentication, offering users a password-free, verification-code-free experience while providing the strongest account security available.
Preparing to Set Up Your Passkey
You can create passkeys on these devices:
- Mobile devices running iOS 16.0.0+ or Android 7.0+
- USB security keys supporting FIDO2 protocol (U2F-compatible hardware that plugs into USB ports)
How to Set Up a Passkey for Your Account
Step 1: Complete Identity Verification
- Navigate to Full Features > Profile & Settings > Security Settings > Passkeys > Enable
First-time setup requires:
- Email/SMS verification codes
- Biometric authentication (face/fingerprint)
Step 2: Create Your Passkey
Choose one of three methods:
Method 1: Use Current Device
Tap Continue → Complete biometric authentication/enter device password
Method 2: Use Another Mobile Device
- Select Other Options > iPhone/iPad/Android
- Scan QR code with secondary device → Authorize access
Notes:
- iOS: Passkeys sync across devices sharing the same Apple ID
- Android: Requires Google services access
Method 3: USB Security Key (iOS Only)
Select Other Options > Security Key → Follow on-screen instructions with inserted key
Step 3: Verify & Login
View passkey details in your security settings. Future logins allow password-free access via passkey authentication.
Using Passkey Verification
Two primary scenarios:
Current Device Verification
