/etc/shadow 2nd column with !!

Hi All,

I have this /etc/shadow below:


What does !! mean on the second column? Is it password or can the userid login or what?

Thanks in advance.

If i remember
1 Is name user or name service
2 can be crypted password or * or ! or !!
(*,!!,!)is string flag to inform as system process or daemon process and other elements ....
3 is userid
To really understand
execute man adduser , after some learn
make several type users and open /etc/shadow to observe relation effect resulting
also see /etc/include/shadow.h for struct ....
Best regards
