The documentation of KWallet says it is possible to use separate wallets for storing local and network passwords. However it does not explain how local and network are defined. Additionally, although one can create a separate local wallet, there seems to be no way to tell a program "you should use this particular wallet" and all programs actually use the main wallet. In other words - no application ever asks to store/read data in the local wallet.

Practically this means that this function exists just as an idea and not as something usable.

Why this is a problem:

If one wants to store local (LAN) credentials it makes sense to put those in the local wallet, separately. For example when using Dolphin in a LAN. But that is impossible as Dolphin always stores data in the default wallet (as explained above). So if at the same time one allows a browser (say chromium) to use the same wallet, this means that the browser gets full access to local passwords too. And that is a potential security problem. We must be able to isolate sensitive data per application.

I have tried to search for info without luck. It seems nobody can answer the question "How to use separate wallets for particular programs". Even asking in the KDE forum didn't help:

I hope someone familiar with the development of KWallet can look into this and possibly provide info and/or a fix.

I am using openSUSE Leap 42.1 with Plasma 5. Everything is up to date with the official repos.
