but now I want the system to ask me for a password when I log in and

for root as well when I try to su in the bash prompt. how can I enable both this things? Krishnakant.

Hello Krishnakant,

You can do that simply by :

# sudo passwd root

This will enable a password for the root user.

Also, please go through the documentation here :
