I have Debian GNU/Linux 9.0 installed on my PC and it is login without password (normal and root users), I tried to changed password using passwd command but it is not possible I received only the following message:
Running like normal user $ passwd passwd: password updated successfully Running as root user # passwd myuser passwd: password updated successfully # passwd passwd: password updated successfully
Also in the login window user can login without password.
Anyone has an idea how can I solve this issue?

There is not file /etc/pam.d/password # cat /etc/pam.d/common-password # # /etc/pam.d/common-password - password-related modules common to all services # # This file is included from other service-specific PAM config files, # and should contain a list of modules that define the services to be # used to change user passwords. The default is pam_unix. # Explanation of pam_unix options: # # The "sha512" option enables salted SHA512 passwords. Without this option, # the default is Unix crypt. Prior releases used the option "md5". # # The "obscure" option replaces the old `OBSCURE_CHECKS_ENAB' option in # login.defs. # # See the pam_unix manpage for other options. # As of pam 1.0.1-6, this file is managed by pam-auth-update by default. # To take advantage of this, it is recommended that you configure any # local modules either before or after the default block, and use # pam-auth-update to manage selection of other modules. See # pam-auth-update(8) for details. # here are the per-package modules (the "Primary" block) password [default=1] pam_permit.so # here's the fallback if no module succeeds password requisite pam_deny.so # prime the stack with a positive return value if there isn't one already; # this avoids us returning an error just because nothing sets a success code # since the modules above will each just jump around password required pam_permit.so # and here are more per-package modules (the "Additional" block) # end of pam-auth-update config
