Research company SplashData, recently revealed that the most popular password in 2013 is "123456", displacing "password" to second place.

The firm compiles the annual list using data from hackers to create the top 25 passwords

Adobe receives a mention in the list for the first time as the password "Adobe123" makes 10th place, whilst "letmein" and "trustno1" both drop places.

Andrew Avanessian, VP Professional Services at Avecto, said: "These findings once again highlight the importance of strong, original and unique passwords as a barrier to corporate information. Whilst compliance mandates such as PCI DSS 3.0 dictate the use of suitable passwords, this is a basic security practice that all businesses should follow.

"I am always surprised at the number of businesses that still share passwords between users, or that don't have adequate security policies in place. Without these basic principles, it is much easier for hackers and malware to penetrate the corporate network, and when they find a user with admin rights, there's no stopping the damage they can cause."
