Often in your sketch, there is some sensitive data that you’d like to keep private, which could accidentally become public when published on GitHub or when you share your sketch with someone else via URL.This sensitive information may include Wi-Fi network names and passwords, API key, and so on. But now, you can add a secret tab to your sketch and store your private data there.
This feature has been designed specifically for the Arduino Create Editor.
