I had a similar problem, but its not clear what password prompts you are using, as I dont use these software.
But I guess they have different causes.
You have saved Wifi networks and all just working and will not have borked your Kwallet. But for completion, for auto-unlock kwallet needs to
use blowfish
use an empty or your login password
the wallet needs to be set as default in the systemsettings page (really confusing as the rest is done in the apps window)
But discord may use Gnome keyring, and I think there is no integration to autounlock that on KDE which sucks, as Spotube (I think) and some other apps use it too. You may want to disable keystore if that doesnt log you out.
The other thing with gpu-screen-recorder will probably be a polkit prompt because the app wants access to… you know GPU stuff.
I made a script to fix these prompts by automatically allowing certain polkit actions for users in the wheel group when logged in and not over ssh. Thats basic polkit config. You can add more for things like updating the system, opening kde-partitionmanager, opening virt-manager (this is fixed by adding the user to the libvirt group), mounting and unlocking LUKS drives.
You get the name of the process (hopefully not just “sudo do that” by clicking on “details” in the KDE polkit prompt
So yeah so much without any actual description of the problem or just screenshots of the dialogs and a list of the apps.
For easy debug info targeted towards KDE bugs, i created sysinfo, similar to KDEs kinfo but better and with the option to append app names, package manager query etc.
