Also help me to know nw where it went wrong.

My present config is

#auth     [success=done ignore=ignore default=bad] pam_selinux_permit.so
#auth        sufficient   pam_python.so /lib64/security/howdy/pam.py
auth        substack      password-auth
-auth        optional      pam_gnome_keyring.so
-auth        optional      pam_kwallet5.so
-auth        optional      pam_kwallet.so
auth        include       postlogin

Hi @hemanthch What Fedora Option? In my pam.d no sddm, what app does bring sddm?

You can use the authselect tool to create a new, working PAM stack. It’s likely that sudo authselect apply-changes (which re-writes your currently configured options).

If that doesn’t do it, check the man page for details, or the RHEL 8 documentation, which largely applies. You may find authselect check particularly helpful to start.

I think this will correct the one for sddm (@jpbn, that’s the login/display manager used by the KDE Plasma spin and possibly some other desktops.) If it doesn’t, sudo dnf reinstall sddm should install the “correct” config file (possibly as .rpmnew).
