Grandad’s got a better password than you, kiddo.

In all likelihood, that is. New Scientist doesn’t actually *know* your password, of course. But they know that if you’re over 55, you’re more likely to be secure than if you’re under 25:

People over the age of 55 pick passwords double the strength of those chosen by people under 25 years old. That’s according to the largest ever study of password security, which also found that most of us choose passwords that are less secure than security experts recommend.

Joseph Bonneau, a computer scientist at the University of Cambridge, analysed the passwords of nearly 70 million Yahoo! users. The data had been protected using a security technique called hashing, which ensured he did not have access to the individual accounts. He calculated the password strengths for different demographic groups and compared the results.

A comparison of different nationalities found that German and Korean speakers choose the strongest passwords, whereas Indonesians pick the weakest.

I think Indonesians might be more guessable because Bahasa seems to use fewer letters, and nearly always consonant-vowel-consonant-vowel-consonant (not so big on the schmaltz or freundlichkeit). But that’s just a guess.
