SYNOPSIS
pwunconv [options]
DESCRIPTION
pwunconv reverses the shadow password setup by moving password hashes from /etc/shadow back into /etc/passwd and removing the shadow file. This is the inverse of pwconv and effectively disables shadow password protection on the system.The command is part of shadow-utils and is rarely used in practice since shadow passwords are a fundamental security feature on modern Linux systems. Removing shadow protection makes password hashes readable by all users, significantly weakening system security.

-R ROOT
Chroot directory.
INSTALL
sudo apt install passwd
sudo apk add shadow-conv
CAVEATS
Security risk. Rarely used. Requires root.
HISTORY
pwunconv is part of shadow-utils for reverting shadow passwords.
