Securing your digital assets starts with strengthening your account’s defenses. One of the most effective ways to do this is by linking an authentication app. This two-factor authentication (2FA) method adds a dynamic, time-sensitive layer of protection beyond just passwords, significantly reducing the risk of unauthorized access.
Whether you're using the OKX mobile app or accessing your account through a web browser, the process is straightforward and compatible with popular authentication apps like Google Authenticator or Microsoft Authenticator. Below is a clear, step-by-step guide to help you securely link your preferred authentication app.
Why Use an Authentication App?
Before diving into setup steps, it's important to understand why this matters. Unlike SMS-based 2FA, which can be vulnerable to SIM-swapping attacks, authentication apps generate time-based one-time passwords (TOTP) directly on your device—offline and encrypted.

Linking an Authentication App via the OKX Mobile App
Follow these steps to enhance your account security using the OKX mobile application:
Step 1: Navigate to Security Settings
Open the OKX app and tap on Menu, then go to Profile & Settings > Security. Under Authentication Methods, select Authentication App to begin setup.
_Tip_: Look for the Security Center within Profile & Settings for quick access.
Step 2: Verify Your Identity
To proceed, you'll be prompted to verify your identity via phone number or email. This ensures only authorized users can modify sensitive security settings.
Step 3: Install an Authentication App (If Needed)
If you haven’t already, download a trusted authentication app such as Google Authenticator or Microsoft Authenticator from your device’s app store. Once installed, keep both the OKX app and your chosen authenticator open during setup.
Step 4: Connect the Apps
In the OKX app, copy the setup key displayed on-screen. Then:
- Open your authentication app
- Choose “Add Account” (usually via a + icon)
- Select “Enter a setup key” or similar option
- Paste the copied key, or scan the QR code shown in OKX
_Pro Tip_: Interfaces vary between apps—always follow in-app instructions for best results.
Step 5: Confirm Setup
After adding the account, return to the OKX app and tap Continue. Open your authentication app again, locate your OKX account, and enter the 6-digit verification code currently displayed.
Step 6: Finalize
Once verified, your authentication app will be successfully linked. From now on, you’ll need this code every time you log in or perform sensitive actions.
✅ Optional: Enable biometric lock (e.g., fingerprint or face recognition) within your authentication app for added local device security.
Linking via the OKX Website
You can also set up 2FA directly from a browser—ideal if you're managing your account from a desktop.
Step 1: Access Your Account
Log in to your OKX account at okx.com, click your profile icon, and select Security from the dropdown menu.
Step 2: Locate Authentication App Option
In the Security Center, find Authentication App and click Set Up.
_Tip_: The Security Center houses all critical protection tools—bookmark it for future reference.
Step 3: Prepare Your Authenticator
Open or install your preferred authentication app (e.g., Google Authenticator). Once ready, click Next on the setup page.
Step 4: Scan QR Code or Enter Key Manually
Use your authentication app to either:
- Scan the QR code displayed on-screen, or
- Manually input the provided setup key
_Reminder_: Each app has unique navigation—refer to its help section if unsure.
Step 5: Confirm Connection
After adding the account in your authenticator, return to the browser and click Next. Retrieve the 6-digit code from your app and enter it into the prompt.
Step 6: Completion
Upon successful verification, your authentication app is now active. You’ll see a confirmation message indicating that 2FA is enabled.

Frequently Asked Questions (FAQ)
Q: Can I change my authentication app later?
A: Yes. You can disable or switch apps at any time through your security settings. However, for safety reasons, fund withdrawals and P2P trading will be temporarily restricted for 24 hours after any change.
Q: What should I do if I lose access to my authentication app?
A: Immediately use any backup recovery codes you saved during setup. If unavailable, contact OKX support with verified identification to regain access.
Q: Is it safe to use third-party apps like Google Authenticator?
A: Absolutely. These apps do not store data on servers—they generate codes locally on your device, making them highly secure and privacy-focused.
Q: Do I still need SMS verification after linking an authentication app?
A: While SMS can remain as a secondary option, using an authentication app is strongly recommended as it's more secure than text-based codes.
Q: Can I use multiple devices for 2FA?
A: Not simultaneously. The same secret key should not be reused across devices. If switching phones, properly transfer or reconfigure your authenticator account.
Best Practices for Ongoing Security
- ✅ Back up your recovery codes in a secure offline location.
