I was challenged by a cyber security professional this evening as we discussed how he could literally “sniff” ( his word for his software) my details. Got me thinking about the need to generate unbreakable passwords. To do this I have found two sites which may be of interest.

http://passwordsgenerator.net/ generate strong unbreakable passwords!
Obviously you are not going to remember a strong , unbreakable randomnly generated password but where security and important information are concerned this would give you peace of mind.
