# 1.4.5 OKX API Binding Tutorial

**For security reasons, the API secret will be displayed only 1 time. After closing the window, the API will not be available. Make sure to save the key in a safe place.**

❗️❗️**For a correct API binding we recommend to use the web-version of the exchange, not the app**❗️❗️

First you need to download the BingX app or visit the official website of the exchange: <https://www.okx.com/>&#x20;

If you are already a registered user, then log in to your existing account on the exchange. If you don't have an account, you'll need to register first and pass KYC.&#x20;

After successfully logging in or registering, press on the account icon in the upper right corner.&#x20;

In the next section “Passphrase” specify your secret phrase and save it to a safe place.

*This section is required to view information and access the API. Keep it safe and create a new API key in case the passphrase is lost. The passphrase must include uppercase and lowercase letters and be 8-32 characters long. Spaces and special characters are not supported.*
