1. After logging into the Binance account, click [API Management] in the user center drop-down box. After entering the API management page, set an API key (ie API name), and click [Create].
* Security Tip: Before creating the API, you need to bind the secondary authentication.
2. Click [Get code], enter “Phone verification code”, “E-mail verification code” and “Google verification code”, then click [Submit] to create an API.
3. Remember to store your Secret Key somewhere safe. It will not be shown again. Due to security reasons, please do not share this key with anyone. (If you forget the Secret Key, you will need to delete the API then re-create a new one.)
