Since using konqueror with webenginepart, konqueror no longer stores or reads passwords from kwallet.
E.g. I open https://login.qt.io/login and konqi does not fill in my data although they are stored and I see them with kwalletmanager5

What I find strange is that I do not see konqueror in the list of applications in the "Applications" tab of kwalletmanager5.

And yes, I have also checked konqueror settings -> Web Browsing -> offer to save website passwords
