AlmaLinux OS 9 PAM must be configured to use a sufficient number of password hashing rounds.

An XCCDF Rule

Description

Passwords must be protected at all times, and encryption is the standard method for protecting passwords. If passwords are not encrypted, they can be plainly read (i.e., clear text) and easily compromised. Using more hashing rounds makes password cracking attacks more difficult.
