The new series of Rip Off Britain is well underway, airing on BBC1 throughout September and October.

As usual I’ve been appearing with the team giving expert advice on safe and savvy use of technology and the internet.David McClelland, Tech Expert, BBC Rip Off Britain

It’s been a busy series for me: as well as appearing in the Popup Shop in the West Midlands I’ve been covering a variety of topics including online password security, nuisance call blockers, how online advertising works, and taking care when connecting to public Wi-Fi hotspots.

One item that has generated a lot of interest is online password security.

On average we have 26 online logins each in the UK, with 25-34 years old managing up to 40. Most worrying of all is that Experian, who conducted the research, found that despite the number of accounts we manage, we each use an average of just 5 different passwords!

When researching the item I tried to count how many online accounts I owned: I stopped when I reached 90. I know I’ve many more, and it’s a number that’s only going to grow. I also realised that it’s very rare that I go back to delete an account that I no longer use, particularly if it’s with an online retailer I’ve used just the once to buy a gift.

In the show I ran a workshop in a shopping centre to highlight the challenges of safely managing our online accounts. Of course, it’s a big subject with too much to share in a short item on television, so to help further I put together a leaflet.

My “How to manage and remember your online passwords” leaflet contains tips on how to make your online accounts as safe as possible, including choosing passwords and passphrases that are difficult for fraudsters to guess or crack, and an introduction to password management software. You can download the leaflet from the BBC website.
