While two-thirds of the Dutch say they are concerned about the safety of the internet, many of them break simple rules about keeping their information private, according to justice ministry research.

Around 50% delay installing software updates and four in 10 use free public wifi networks, the research, quoted by RTL Nieuws, found.

Many people use the same password for their email, bank account and webshops, and one in 10 use the same password for over 10 different internet accounts.

‘People think it only logical to lock their back door, but don’t take the same approach to their digital doors,’ justice minister Ferd Grapperhaus told RTL Nieuws in a reaction.

The research, carried out by PanelWizard, involved around 1,000 people.
