WiFi - Arduino Sketches: Tools and Techniques for Programming Wizardry - page 190

Server: 334 UGFzc3dvcmQ6
Client: <password>
In your sketch, add some form of authentication, maybe like this:
client.write("auth login");
client.write("<Base64 login>");
client.write("<Base64 password>");
Summary
In this chapter, you have seen how to install and use Arduino's WiFi board, how
to scan for wireless networks, and how to connect to a wireless network. I have
shown how to read from a sensor using a single wire, and how to connect to an
SMTP server to send an e-mail. In the next chapter, you will see more about SD
cards: what they are, how they can be used, and how to read and write data to
and from these devices using an Arduino.
