@ cmannett85 "Use a bloody password manager!"
This is the core of the problem, only emphasised by this FTA, "Ollie Whitehouse, technical director at NCC Group, added: “This latest hack is yet another example of why people should use different and strong passwords for all online accounts due to the lack of transparency with regards to how they are held."
Every site expects people to register before they can use it (it's unusual to find a website that allows express checkout without registering as that would
stop their data harvesting impair the user experience), you're expected to use a completely different password for each site, and every password must contain a capital, a lower case, the number you first thought of, a punctuation, an emoji, and what you did last summer. People are looking at 50-100 passwords just for the regularly used parts of their online time (possibly much more) all of which are near impossible to remember so is it any wonder they pick one "strong" password (as determined by the misguided password policy on the most cantankerous site they use) and reuse it elsewhere. It may help using a different email address for each site but that is a lot to manage for many people and strays into security/obscurity territory.
Password managers are helpful and I believe most of the major browsers offer some kind of "remember my password" functionality (Safari, Firefox, IE, not sure about others) but one breach on the password manager exposes the whole bloody lot. Perhaps the most secure password manager is a small notebook in a kitchen drawer?
My concern is that these kind of things push people towards third party authentication e.g. login with your Facebook account. The idea that Zuck becomes the password gatekeeper to the interwebz is just too horrific not just because it also concentrates the target into one place - crack a Facebook account and get access to everything. Facebook only keep things private if it suits them and telling them you log into Amazon, your mobile provider, your telly provider and your utility on a regular basis would be music to his wallet.
I'll leave it to someone else to dig out a link to the XKCD cartoon about passwords.
