SUMMARY
As reported downstream in the Manjaro forums, after Manjaro Unstable updated KDE Frameworks to 6.14 it seems like Kwallet lost my Wireguard private and preshared keys: https://forum.manjaro.org/t/unstable-update-may-2025/177492/40?u=majormayer
Since I activate the the connection automatically, a dialog appeared after every boot that prompts for "some" password, without any explanation which password or rather key is actually meant (it overwrites/ sets the private key actually).

I was able to fix the problem by setting the correct values using the NetworkManager GUI.
The VPN applet in KDE's settings didn't allow me to apply my changes for whatever reason (the apply button was in disabled state, no matter what I entered, without any explanation).

STEPS TO REPRODUCE 
Disclosure: I haven't tried to reproduce this problem, I just wanted to report it, because the VPN connection was working for years already.
1. Set a Wireguard VPN using KDEs settings
2. Upgrade to KDE Frameworks 6.14
3. Try to connect again

OBSERVED RESULT
A dialog appears that asks for some password to establish the connection

EXPECTED RESULT
The connection should be established without any new keys or passwords

Operating System: Manjaro Linux

ADDITIONAL INFORMATION
Please have a look in the Manjaro thread that I linked.

The weird password dialog seems to be reported here as well: https://bugs.kde.org/show_bug.cgi?id=494264

This is probably BUG 494264 triggered by BUG 502808.

Comment 3 major-mayer 2025-05-17 08:58:18 UTC

Okay, if you say so.
I think I worked around BUG 494264 in the past, by only selecting one user that can connect to this VPN connection instead of all users.
In the latter case, I also had the problem with this prompt IIRC.

But might be that the other bug triggered it one time and I then broke the settings completely by entering my user login password.
Although I wonder why this works again now without any new updates to Kwallet, after I fixed the settings once.

Comment 4 michaelk83 2025-05-17 09:19:24 UTC

There was a big refactor for 6.14, so it's also possible that just that transition alone caused the hiccup. And once you set the settings again, then it's back to normal. But in any case, I think the root cause has already been reported elsewhere.

Comment 5 major-mayer 2025-05-17 09:28:47 UTC

All right, makes sense.
