He also criticised websites which bar people from being able to paste their passwords online, saying it was “completely pointless” and actually “damaging” security. The head of the National Cyber Security Centre has warned people are struggling to remember their internet passwordsCredit:Damian Dovarganes/AP Photo Mr Martin, speaking as the NCSC was officially opened by the Queen, said: “We have got to make it easier for people to operate safely. We did some work where we worked out what are we asking people to do.”We worked out what we were asking every British citizen to do is memorise a new 600-digit number every month. I don’t think I could do that, none of my best people could do that.”There are password managers out there, there are ways you can look at your exposure online, you can work out what you really care about.”He said people should use password managers to handle their security. Ciaran Martin said internet companies must make it “easier” for people to use the internet safely and admitted that even his “best people” would not be able to remember all the lengthy passwords that internet companies demand.He said that his centre has recently worked out that demands for regularly changing, long passwords using numbers, capital and lower case letters, people are being asked to memorise a new 600-digit password every month under official guidelines.He also criticised websites which bar people from being able to paste their passwords online, saying it was “completely pointless” and actually “damaging” security. He said there was also concern about cyber security from British political parties after American intelligence agencies said Russia carried out hacking attacks on the Democrats to try to sway that country’s presidential elections.Mr Martin said political parties had made approaches to the NCSC to see if they could get advice on security.He said: “There’s talk about it. We’ve had some approaches and we would expect to be offering seminars and that sort of thing in the future.”We expect to be asked and we will be happy to.”Protecting the electoral and democratic systems was “up there with the top priorities”, he said.The NCSC, which is part of the Government electronic spy agency GCHQ, will spearhead Britain’s efforts to fend off cyber attacks.Speaking at the launch event, Chancellor Philip Hammond said cyber attacks are increasing in frequency, severity and sophistication.He also warned that households around the country are vulnerable.”The average British home has eight devices connected to the internet,” he said.”This provides enormous potential for day-to-day attacks, from electronic data theft to online ransom.” Ian Levy, technical director at the NCSC, said asking members of the public to remember so many passwords was “dumb”, but password manager programs make life “so much easier”.He said: “That’s the short-term answer to make the current pain go away. If you’ve got a vault of all your passwords, you need to remember one. It syncs across all your devices.”We are about to publish guidance on how to select a good password manager.” It is one of the frustrations of modern life: the need to recall an ever-growing list of internet passwords.But those who struggle to remember which combination of their pet’s name, birthday and football team unlocks their online shopping can now take heart – so do the country’s top cyber spies.The head of Britain’s new National Cyber Security Centre (NCSC) has admitted that people are now required to remember so many passwords that he would struggle to recall them all himself.
