Just follow the following technique exactly as it is:
This is the contribution made by some dedicated forum members.Security set-up for Puppy 2.16 onwards
1 Open console type 'passwd'. enter your new password twice.
2 Run 'lock' on desktop and enter password from step 1
*you may want to select 'blank' from the config to save on processor usage
3 edit /etc/inittab to look like this:
::sysinit:/etc/rc.d/rc.sysinit
tty1::respawn:/sbin/getty 38400 tty1
tty2::respawn:/sbin/getty 38400 tty2
::ctrlaltdel:/sbin/reboot
*this keeps someone from killing lock with ctrl+alt+backspace and logging back in automatically and also gives the option on bootup to enter 'root' and 'password'.
If you want just thank them all.
Thank you.
