How to use Kwallet as default keyring

I am using KDE desktop (plasma 5 ) environment with opensuse leap 42.1. Many programs in my system use native keychain to store password like (JetBrain products). But when saving the password, I notice that the default keychain for my system is genom-keyring. How to configure my system to use KWallet as default keychain. I have uninstall genom-keyring with all its dependencies and now the system does not recognize any default keychain. How can I make Kwallet the default keychain? Another question how can I avoid typing the paraphrase every time I sign in my account (to open the wallet) Thank you very much
