single user mode
 

HI,
1)How to give password to single user mode ?
2)If the O.s is installed then how to give password to single user mode?

Which OS are we talking about and what are you trying to acheive?

Single user mode does not normally need a password, or it uses the root password. AFAIK: It is usually listed in the grub menu as "recovery" mode and in a gdm login screen as "failsafe terminal". initV systems let you telinit to single-user mode. (man telinit)
