The pam_unix arguments are configured through the active authselect profile so that the change is durable; editing /etc/pam.d/system-auth or /etc/pam.d/password-auth directly is not durable, because authselect regenerates those files (see the section overview for the authselect profile model). Set yescrypt, the default and recommended algorithm on this platform: 1. Ensure the system is using a custom authselect profile. If it is still on a stock profile, create and select one first, as described in the section overview. 2. On the pam_unix.so line in the password stack of the active custom profile templates (/etc/authselect/custom/<profile>/system-auth and /etc/authselect/custom/<profile>/pas…
