前幾天在 Twitter 看到,剛剛在 Hacker News Daily 上的整理又看到:
Fun thing I learned today regarding secure passwords: the password "ji32k7au4a83" looks like it'd be decently secure, right? But if you check e.g. HIBP, it's been seen over a hundred times. Challenge: explain why and how this happened and how this password might be guessed

老外在研究的時候發現這個密碼看起來夠長 (12 個字),而且也還算安全 (有英文與數字,看起來無意義),但卻發現被大量重複使用,而不只是單一帳號在用,就很好奇發生這是什麼東西...
對於台灣人來說應該是很熟悉了,這是注音輸入法的「我的密碼」:

非拼音類的輸入法應該都會產生一樣的困惑...
