Wifi authentication via SMS not such a good idea

Popped into Asda this morning (wicked prices on fresh papayas) and noticed free wifi, offered via EE.

Terrific, I thought! Tapped the ‘Get Online’ button, entered my phone number into the subsequent dialog saying EE would send me a text message with an authentication code.

Equally terrific! Except, I was inside a huge store where the cellular signal was just about non existent. So no SMS message could arrive…

Slight #Fail, EE and Asda :)
