"Scientifically Proven Password Security," says PINoptic on its website. Now, I'll rest down my sarcastic jokes when it has been "scientifically proven," or otherwise the jokes are on me. ;-p
Instead of having a PIN or password, you have a series of pictures or icons that make up your 'picture story password'. When you come to enter your picture story password, multiple pictures or icons are displayed beside discrete symbols (alphanumeric characters for instance). You enter the symbols that are related to your picture story password to gain access. Each time you are asked for your picture story password the pictures, icons or symbols will be in a different place meaning that you will be entering a one-time-password each time.
