Kali Linux password fail
From some other boot, ie if kali on emmc, use SDboot, if k on SD, emmc boot or card reader
mount kali / somewhere, cd kali/etc, edit shadow (kali/etc/shadow)
Look for the line with your login name,, for example (for d,, changed)
d:$6$HAGjYB4WRfi91DJ8$l0wAB0N.IalV4hlvsiLjm/MEbi7TK5Jhgi5hyzBVCimYyS5TlYeLuEp0:17525::99999::::
make it
d::17525::99999::::
ie,,$USER::other stuff,, nothing between first 2 colons, this will be passwordless
Do make a backup first, in case you really screw up
