Using two-factor authentication (2FA) is highly recommended. By enabling 2FA, you are adding an extra layer of security to your account, giving you the confidence that your funds are safe. Huobi US offers several methods of 2FA. Using both methods of 2FA at the same time will make your account significantly more secure.

• Google Authenticator (more secure).
• SMS (less secure).

Google Authenticator

Google Authenticator or similar authenticator apps provide the most secure configuration for 2FA. These do not require phone reception or internet access once set up. Google Authenticator generates a unique authentication code valid for only thirty seconds for each app that it is bound to. Google Authenticator is more robust than SMS verification, and because it is not associated with your phone number (although we do require a phone number to be registered to buy or sell virtual currencies), it is not susceptible to phone number porting attacks. The authentication code is used for added account security for login, withdrawal, and security settings actions.

After you have downloaded the Google Authenticator app on your phone, log in to your Huobi US account.

1. Under the account tab, select “Account and Security.”
2. Look for where it says Google Authenticator in the Two-Factor Authentication section, select “Add.”  
3.  Open the Google Authenticator App on your device and scan the QR code displayed.
4. Enter the 6-digit verification code generated from your GA and click “Add” to complete the initial setup.

SMS

By using SMS verification, you will be sent a time sensitive access code (via SMS text message) to your connected phone number every time there is an attempt to log in to your Huobi account. By enabling SMS verification, your account is more secure than only a username and password.

1. Under the account tab, select “Account and Security.”
2. Look for where it says Phone in the Two-Factor Authentication section and select “Add.”    
3. Input the phone number you’d like to link to your account and click “Send” to have the SMS verification code sent to that number.
4. Input the code you received and click “Add” to complete the initial setup.
