authconfig:tldr:75154
The command authconfig --update --passalgo=${algorithm}
is used to update the password hashing algorithm used by the system authentication configuration.
The command begins with authconfig
, which is a command-line tool used to manage system authentication configuration in Linux systems.
The option --update
is used to update the system authentication configuration. It instructs authconfig
to apply any changes made in the command.
The option --passalgo
is followed by ${algorithm}
. Here, ${algorithm}
is a placeholder indicating that the user should specify the desired password hashing algorithm. The password hashing algorithm is responsible for securing the stored passwords on the system.
By using this command and providing the appropriate algorithm, the system's password hashing algorithm will be updated to the specified value, increasing security, and potentially improving performance.
