Password reset via u-boot (init=/bin/sh) possible?

[wdt]

Since you seem to so much problem remembering, maybe you should WRITE IT DOWN
and then hide the paper, if you can remember where you hid the paper
(user:password is the normal syntax)
----
In Linux the password is stored in /etc/shadow,the fields separator is ":" (colon)
the 2nd field is the hashed password, aprox 60+ chars
if you make
userName:60chars:and_more into
userName::and_more
then userName has no password, just hit enter
---
you do have to be root/sudo to edit shadow
