I’m looking for some way to change KWallet’s password automatically when the account’s passwords changed. Maybe even a prompt that just asks the user to sync their new password.
The accounts in question are tied to the Active Directory and they expire every 3 months.
Unrelated, but may happen before logging in to the system due to SDDM not having a prompt for expired password.
This exists. When you change your password using System Settings > Users, you get prompted to change your wallet password to match the new user password.
Doing it automatically is not possible at the moment though.
