On opensuse forums, I often see complaints about KDEwallet (or “kwallet” for short). It can be annoying at times. In this post, I’ll indicate ways of keeping it under control.
While this is oriented toward opensuse, it should also apply to other distros with one caveat. In opensuse, some of the applications have their settings and configuration under the directory “$HOME/.kde4”. For other distros, it is more typical to use “$HOME/.kde” (without that final “4”). So just adjust my suggestions accordingly.
Starting with Leap 42.1 (and with Tumbleweed), opensuse now supports Plasma 5. And Plasma 5 keeps its configuration under “$HOME/.config” and under “$HOME/.local”. But there remain some older applications with configuration in the old location.
To further complicate things, there are now two versions of “kwallet”. I’ll call them “kwallet4” for the old version still used by some older software, and “kwallet5” for the newer version (for Plasma 5). That both wallets are there, and that they might independently prompt you to open the wallet, is part of the confusion.
