Fortunately, there are almost twenty per cent of computer users who use a password for only one site, according to the security firm Sophos.
This research found that three years ago there were an estimated forty one per cent who used the same password for all of their access.
This would indicate that the message is getting through, but not nearly as fast as everyone in the internet security industry would like.
Passwords are a problem for computer users, as there are many applications that require a username and password to access them.
Therefore it is easier to pick something familiar, but passwords that are based on something personal can be easily guessed.
