The author of zxcvbn acknowledges this weakness (and others) here: https://tech.dropbox.com/2012/04/zxcvbn-realistic-password-strength-estimation/ https://tech.dropbox.com/2012/04/zxcvbn-realistic-password-s... zxcvbn currently only supports English words, with a frequency list skewed toward American usage and spelling. Names and surnames, coming from the US census, are also skewed. Of the many keyboard layouts in the world, zxcvbn recognizes but a few. Better country-specific datasets, with an option to choose which to download, would be a big improvement.
