Securing your online accounts is more critical than ever, and linking an authentication app is a powerful way to add a robust layer of protection. This guide provides a clear, step-by-step process for setting up an authenticator app, whether you are using a mobile device or a desktop web browser.
Using an authentication app, such as Google Authenticator or Microsoft Authenticator, generates time-based, one-time passwords (TOTPs). This form of two-factor authentication (2FA) ensures that even if your password is compromised, your account remains secure.
Important Security Note: You can disable or change your linked authenticator app at any time. However, to protect your assets, certain functions like withdrawals and P2P trading will be temporarily suspended for 24 hours after making such a change.
Setting Up on Mobile
Follow these steps to configure your authentication app using the mobile application.
- Open the application and navigate to the Main Menu. From there, select Profile and Settings.
- Proceed to the Security section. Under Authentication Methods, tap on Authentication App to begin the setup process.
- You will first be asked to verify your identity, typically through a registered phone number or email address, to proceed.
- If you haven't already, download an authentication app from your device's app store. Popular options include Google Authenticator, Microsoft Authenticator, and Authy.
- The application will then provide a secret setup key (a string of text) and a QR code. Copy this key.
- Open your authentication app and choose to add a new account. You can either paste the copied setup key or scan the provided QR code.
- Once you have added the account, return to the application and select Continue.
- Open your authentication app again to retrieve the current 6-digit verification code. Enter this code in the prompt.
- After verification, your authentication app will be successfully linked.

Setting Up on the Web
The process for enabling an authenticator app via the website is similarly straightforward.
- Log in to your account on the web platform.
- Click on your profile icon in the top right corner and select Security from the dropdown menu.
- In the Security Center, locate the Authentication App option and click on Set Up.
- The system will guide you to the setup page. Click Next to continue.
- Use your authentication app to scan the QR code displayed on the screen. Alternatively, you can choose to manually enter the provided setup key.
- After adding the account to your authenticator app, click Next on the web page.
- Retrieve the 6-digit code from your authentication app and enter it in the required field on the website.
- The setup will be confirmed, and your authenticator app will be active.
Best Practices for Authentication Apps
- Secure Backup: Most authenticator apps offer a way to back up your accounts, often via cloud sync or by providing backup codes. Ensure you complete this step to avoid being locked out if you lose your device.
- Device Security: Since your phone now holds a key to your accounts, ensure it is protected with a strong passcode, biometric lock, or both.
- Time Synchronization: Authentication apps rely on your device's time being accurate. Enable automatic time and date settings on your phone to prevent code errors.
Frequently Asked Questions
What is an authentication app?
An authentication app is a software application that generates time-based, one-time passwords on your smartphone. It provides a more secure and reliable form of two-factor authentication than SMS-based codes, as it is not vulnerable to SIM-swapping attacks.
What should I do if I lose my phone or my authenticator app is reset?
This is why backup options are crucial. During the initial setup of your authenticator app, you should have been given a set of scratch codes or configured a cloud backup. Use these recovery options to regain access to your account. You will then need to disable the old 2FA and set it up again with your new device.
Can I use the same authentication app for multiple accounts and exchanges?
Absolutely. A single authentication app can manage verification codes for dozens of different accounts from various services, including other exchanges, email providers, and social media platforms, keeping all your 2FA codes in one secure place.
Why are my verification codes not working?
The most common reason is a time synchronization issue. Ensure your phone's clock is set to update automatically. If the problem persists, try removing the account from your authenticator app and re-adding it using the latest setup key or QR code from your security settings.
Is an authentication app more secure than SMS 2FA?
Yes, significantly. SMS codes can be intercepted through SIM swap scams or other vulnerabilities. An authentication app generates codes locally on your device, making them immune to these types of attacks and providing a much higher level of account security.
