There is a persistent rumour that passwords are going to disappear in a couple of years. The idea has been shared in tech circles and in the media for a few years now. I am, to say the least, sceptical of the impending demise of passwords and their cousins: PINs and passphrases. But even if passwords do disappear in the next 5 or 10 years, they haven't gone away yet, so you need to make sure that you have good ones. Some people say that creating good passwords is too hard, and that password rules make it even more confusing. Tony Neate, the UK's Cyber Security Chief, seems to think that we can't expect normal people to create good passwords, but I disagree.
You can create passwords that are both hard to crack and easy for you to remember. In my opinion, the best way to do that is to base your passwords on phrases rather than single words. In many cases, you can just use the full sentence as-is in a passphrase. and give yourself a clever reminder.
