auth include common-auth
auth optional pam_gnome_keyring.so
account include common-account
password include common-password
session required pam_loginuid.so
session include common-session
session optional pam_gnome_keyring.so auto_start
And then changed all common to system and after rebooting I am unable to login with old password
Ex.
`common-auth to system-auth
common-account to system-auth
I am no expert about sddm, but with forgotten password you can always go on live-usb and chroot into system(super convenient with garuda-chroot). And just change passwords from there.
It’s great when you can track down a problem and fix it on your own without using snapshots.
If you have a spare laptop you can break boot and so on and learn how to chroot and other fixes using searches. Play and enjoy.
