Keeping your critical data safe can be difficult these days, especially when cybercriminals keep coming up with sneakier ways to rip us off.
That's why you really need to be careful with your passwords. If a criminal gets a hold of your credentials they can pretty much do whatever they'd like with your account.
That's why most of us are leery when it comes to giving guests in our home the Wi-Fi password. It's not that you don't trust grandma, you're just afraid that handing your network's password out to anyone could lead to disaster later.
There has to be a better way. Don't worry, there is.
You can post a QR Code around your house, so your guests (and you) can just scan it with an Android phone. It's a secure shortcut with your password hidden inside. When you need it, you scan the QR Code instead of typing in your password.

If you think you don't know what a QR Code is, you do. (See photo above.) It's that odd-looking box that's filled with smaller boxes, which you may have seen people scanning for discounts at the supermarket. QR codes are super easy to use and this cool site lets you create them for free.
QR4 is an online QR code generator for Wi-Fi access that works with Android gadgets.
(Psst: If you're an Apple user, watch the following video to see how you can use this QR code generator.)
To use the site you'll need three pieces of information, which you can get from your internet provider. Or follow these instructions:
First, look at the back of your modem for "SSID." It might be shown as something like, "Wi-Fi Network Name (SSID)." It'll be about a dozen numbers and letters; type those in where it says SSID on QR4's Code Generator page.
Second, type in your password. It might be "Administrator." If you don't know, call your internet provider.
Third, choose your secure network type; the site defaults to WEP, but you may have WPA. If you don't know, ask your internet provider.
Click on the button that says "Generate WiFi QR Code," and that's it. You now have your own, very cool QR Code.
Print it out, and post it around the house. The next time you hear, "What's the Wi-Fi password?" Just yell back, "Scan it."
