Allow short simple password on Ubuntu #12

Open klequis opened 3 years ago

Using Ubuntu 22.04 the method below no longer works.

However, if you use sudo passwd <username> and ignore the message about 'bad password' it will set the password.


Old - doesn't work anymore

from: How to set a short password on Ubuntu?

Bring up a terminal and edit /etc/pam.d/common-password

Change this line:

password    [success=1 default=ignore]  pam_unix.so obscure sha512

to:

password    [success=1 default=ignore]  pam_unix.so obscure sha512 minlen=4

Password also need a certain amount of complexity, as specified by the obscure parameter above.

password    [success=1 default=ignore]  pam_unix.so minlen=2 sha512

removes that check also.

This all presupposes that you think this is wise.

See man pam_unix
