The second of the three keyboard brothers unlike qwerty it is less
frequently used as a password and less likely to pop up in other textual references for example the QWERTY keyboard is not named the ASDFGH keyboard. The zxcvbn is the other brother to asdfgh and is the youngest. Asdfgh has been seen less of because the qwerty line uses 4 of the 5 vowels (or 5 of the 6 if you include "y" as a vowel)
Asdfgh is equally
important to the
world renowned qwerty and the less heard of zxcvbn.
