Welcome to CircuitPython's Web API. Go to the file browser to work with files in the CIRCUITPY drive. Go to the full code editor for a more enriching experience which requires an active internet connection. Go to the serial terminal to see code output and interact with the REPL. Make sure you've set CIRCUITPY_WEB_API_PASSWORD='somepassword' in /settings.toml. Provide the password when the browser prompts for it. Leave the username blank.
