I got the stable release of armbian for the ROCK64, flashed on a sd-card aaaaaaaand ... wrong password. root + 1234 doesn't work.   Has the password been changed? I tried the following combinations: root:1234 ROOT:1234 root:!"§$ (german keyboard, don't know whats on en) armbian:armbian rock64:rock64   All passwords are incorrect.   I try it with xenial and strech.
