First off, I hope everyone had a great holiday season, and are looking forward to the new year. I'm sure many of us had relatives come over to our house, with their phones and computers and such. You have a WiFi network in your house, but it's password protected. Here comes the question: "Hey, what's your WiFi password?"
Usually, many of us would either grab the password from the back of our routers (which is a bad idea; don't have your password in the open where someone can get it easily), or dig up a piece of paper somewhere (a better option). Either way, there's an easier option: QR Codes!
