Short article with a simple message. Be careful when punching in your phone unlock code. We do it all through the day, and very rarely are we mindful of who is around us at the time. Are you comfortable leaking your phone access password to people all day? Aside from your simple phone access password, are there any other security measures to stop a thief or hacker gaining full access to your contacts, emails and other private information. As an experiment, I actively attempted to snoop on anyone typing in their phone unlock code, whilst I travelled to in to central London and back today. I lost count eventually but the result was well over 40 just on the journey there. It was also harrowing to see that almost everyone (perhaps over 90%) on the underground took out a phone or tablet at least once on the train journey.
