How to set up a passkey on OKX? (Login security)

Understanding Passkeys on OKX

1. Passkeys are cryptographic credentials that replace traditional passwords for logging into OKX accounts.

2. They rely on public-key cryptography stored securely in device operating systems like iOS, Android, or macOS.

3. OKX integrates with the FIDO Alliance standards to ensure compatibility with Apple Wallet, Google Password Manager, and Windows Hello.

4. A passkey cannot be phished or reused across platforms, making it inherently more secure than SMS or email-based 2FA.

5. Users must have an OKX account verified at Level 2 or higher to access passkey setup in the security settings.

Navigating the OKX Security Dashboard

1. Log in to your OKX account via the official website or mobile app using your current authentication method.

2. Tap or click the profile icon in the top-right corner and select “Security Center” from the dropdown menu.

3. Scroll down to the “Login & Authentication” section and locate the “Passkey” option.

4. Click “Add Passkey” — the interface will prompt you to confirm your identity using your existing 2FA method.

5. After verification, OKX displays a QR code or initiates device-native credential creation depending on your platform.

Creating a Passkey on Mobile Devices

1. On iOS, scanning the QR code opens a system prompt asking to save a new passkey; tapping “Continue” stores it in iCloud Keychain.

2. Android users with Chrome version 108+ or newer receive a “Save passkey” banner after scanning, which syncs via Google Password Manager.

3. The device prompts for biometric confirmation (Face ID, Touch ID, or fingerprint) before finalizing registration.

4. Once saved, the passkey appears under “Saved Credentials” in device settings with the label “OKX Exchange”.

5. No backup phrase or recovery key is generated — deletion from the device permanently removes access unless another passkey is registered.

Using Passkeys During Login

1. At the OKX login screen, enter your registered email or phone number and proceed to the password field.

2. Instead of typing a password, click the passkey icon (a shield-shaped button next to the password input).

3. Your device automatically detects the OKX domain and surfaces the matching passkey in the OS credential selector.

4. Confirm with biometrics — no additional codes, app approvals, or time-based tokens are required.

5. Upon successful verification, the session initiates immediately without redirecting to external authenticators or email confirmations.

Frequently Asked Questions

Q: Can I use the same passkey on multiple OKX accounts?No. Each passkey is bound to a single OKX account and tied to the domain and user handle during registration.

Q: What happens if I factory reset my phone after setting up a passkey?The passkey is erased permanently unless it was synced to iCloud or Google’s cloud service and restored during device setup.

Q: Does OKX support passkeys for API key management?Passkeys apply only to user-facing login flows. API authentication continues to require HMAC-SHA256 signatures and secret keys.

Q: Why does OKX not allow exporting or backing up passkeys manually?FIDO specifications prohibit exportable private keys to prevent offline brute-force attacks and maintain hardware-bound security guarantees.
