Hi,
I think this will help:
# From console, interrupt the boot routine:


         Hit [Enter] to boot immediately, or any other key for command
prompt.
         Booting [kernel] in 9 seconds...

         < Press the space bar at this point >


# Enter into single-user mode:

         Type '?' for a list of commands, 'help' for more detailed help.
         ok boot -s


# Enter the shell:


# Mount the virtual file systems (for JUNOS 5.4 and above, it is not
necessary to mount the jbase package, however the other packages still
need to be mounted):

         NOTE: to go to multi-user operation, exit the single-user shell
(with ^D)
         # cd /packages
         # ./mount.jbase
         Mounted jbase package on /dev/vn1...
         # ./mount.jkernel
         Mounted jkernel package on /dev/vn2...
         # ./mount.jroute
         Mounted jroute package on /dev/vn3...


# Enter recovery mode:

         # /usr/libexec/ui/recovery-mode


# Enter configuration mode and either delete or change the root
authentication password:


         root> configure
         Entering configuration mode

         [edit]
         root# delete system root-authentication

# Commit the changes, and exit configuration mode

         [edit]
         root # commit
         commit complete

         [edit]
         root at router# exit
         Exiting configuration mode

         root at router> exit


Exit recovery mode and enter "y" when prompted to reboot the system:

         Reboot the system? [y/n] y
         Terminated

The system now reboots and changes made to root authentication are
activated.
