WebREPL (REPL over WebSockets, accessible via a web browser) is an experimental feature available in ESP32 port. Download web client from https://github.com/micropython/webrepl (hosted version available at http://micropython.org/webrepl)...

• turn the WebREPL services on and off
• display the current IP of the device
• Create a random password and displays it
