Comment:
Since `LibSecretKeyring::isAvailable()` does *not* check if secret service is available, only that the library is installed (it seems the library doesn't provide any way to check availability of the service), the only reasonable fix seems to be changing the order of the tests as in:
```diff
     default:
+        if (isKwallet5Available()) {
+            return Backend_Kwallet5;
+        }
         if (LibSecretKeyring::isAvailable()) {
             return Backend_LibSecretKeyring;
         }
         if (GnomeKeyring::isAvailable()) {
             return Backend_GnomeKeyring;
         }
-        if (isKwallet5Available()) {
-            return Backend_Kwallet5;
-        }
```
Note that setting `DESKTOP_SESSION=kde`, etc. might have some undesirable side-effects, so this patch should be preferred. 

Otherwise, there's no way to use any other backend than libsecret if `libsecret` is installed [1] , so you need to install a secret service provider. I could find two in void:
- `gnome-keyring`
- `keepassxc` (depends on #28020 to work)

Meanwhile I was using `kwallet` only because `qtkeychain-qt5` did not work with `gnome-keyring before. With the current `qtkeychain-qt5` now `gnome-keyring` works out of the box for me (just install it, no configuration necessary as long as `libsecret` is installed). The alternative `keepassxc` seems to work, but I didn't like it (cf https://avaldes.co/2020/01/28/secret-service-keepassxc.html for a guide).

For `pass` users, there's this: https://pypi.org/project/pass-secret-service/ (source here: https://github.com/mdellweg/pass_secret_service) but I don't know if it works.

[1] for me `libsecret` is an (indirect) dependency of `mediainfo` (surprising, as I only use the command line tool).
