user with no password

How to create a user with no password ?

[Arunvijai_4 · Accepted solution]

Create a user with normal password then, edit /etc/passwd and remove the entries in the second field (separated by colons) for the particular user.

But, Its a big security hole :(

Hi,

For any existing user or new user after creating account do

#passwd -d username


For this to work the system shall not be a trusted one.

One more way to do this as follows,

# passwd -d where in -d Allow user to login without a password by deleting it. In untrusted mode this unlocks/activates the user account if found locked/deactivated.

When you create user as,

# useradd

then it will not have any username.

You can check it as,

# passwd -s

NP will be the status that it is not having any password.

You can use logins -uax to get the status also.

#passwd -d

is the way !

hi Shiv,
As the others's mentioned ;
passwd -d
but it is really unsecure
Good Luck,

[Frank de Vries]

This to delete a password:

passwd -d (Allow user to login without a password by deleting it)
Thus:
passwd -d

We often use just a carriage return for
a password, this still requires
either an action by the keyboard or
a standard input < CR when scripted.

It is a little bit more secure, as the
CR is a non printable character.
So it looks like there is nothing.

see what is best for you.

hi shiv,

why would you want to create user with no password?


Note that you may also wish to use SAM to specify the user cannot change his/her password..

kind regards

Hi Shiv ,

You can use # passwd -d username


-d Allow a user to login without a password by deleting it.
In untrusted mode this unlocks/activates the user
account if found locked/deactivated.



To check if your system is trusted or not , you can use this command:
# cd /usr/lbin
# ./getprdef -r



Cheers,
Raj.

Hi,

#useradd -d /export/home -s /usr/bin/ksh

#passwd -d

or..

vi /etc/passwd
user_name:xxx:

(erase the characters "xxx" b/w two colon"

save and come out..

This will help to resolve ur issue..

cheers
