As a security measure, enabling 2FA is required to manage your withdrawals, deposits, and your API keys on your Crypto.com Exchange account.
Visit crypto.com/exchange and select the Log In button (upper right-hand corner).
Go to your Profile and select Security > Account Password and 2FA. Under 2-Factor Authentication, you will see the button to Enable 2FA.
A screen will appear and provide you with more details. Below are steps to help you enable 2FA.
Step 1: Download and install the Google Authenticator or Authy app in App Store (for iOS) or Google Play (for Android).
Step 2: A QR code and 16-digit key will be shown on the page. Open your authenticator app and click the symbol【+】on the top right-hand side to scan the QR code, or you can manually enter the '2FA 16-digit key.'
Step 3: The 16-digit key will not be shown again and is unique for each setup. You will need the key to re-bind your account; otherwise, 2FA will need to be disabled and enabled again.
Step 4: In your app, you will see a 6-digit code. Enter the code into the Crypto.com Exchange 6-digit code field. Enable 2FA when ready.
How do I re-enable 2FA if I no longer have access to my authenticator app？
If you have stored the 16-digit code which was generated on the Crypto.com Exchange website when you enabled the Google Authenticator for the first time, you can re-enable your Authenticator by adding the key to the app manually.
If you haven't stored the backup key, you will need to reset your 2FA.
