Sharing long wifi passwords are not fun. With the latest smartphones, you can use QR codes to share WiFi network passwords and eliminate typing long, hard-to-spell passcodes. Use this doc to generator your own QR code image to share with friends. This is a great way to share your phone's mobile hotspot, or your home wifi when friends are over. If you need the QR code on the go, use the Coda mobile app or save a screenshot of your generated code.
