Allowing accounts without passwords
Two parameters located in /etc/default/passwd
control the existence of passwords:
Accounts without passwords are a major security risk.
If set to YES, all users must have a password.
Any user without a password is asked for one
at the first opportunity permitted by
the password expiration set for that user.
(That is, users without passwords
cannot change their NULL passwords
if password aging is enabled for them
and the minimum time before a password can be changed
has not elapsed.)
When set to YES, this keyword
makes passwords mandatory for all logins
Removing the requirement for passwords does not delete
existing passwords. The administrator must change each
password as described in
``Setting or changing a user password''
using the Remove Password button
