I recently started using Lockwise as Password Manager for my Firefox and Android. Now the only Passwords I still need to enter are the ones outside of my Browser on my Desktop. Is there any way to setup Lockwise (or other Password Managers in General) instead of KDE Wallet as Keyring system? So far, I've only had Problems with KDE Wallet system - the only thing it seems to do correctly are WiFi Passwords. There are quite a few other applications where I should enter a password, and while sometimes KDE Wallet knows it's being requested (for many programs it doesn't), it never actually enters passwords.
Is there generally in Unix (Kubuntu 20.04 (KDE) in my case) the possibility to use Password-Managers for applications, like it's possible in Android? (If not, why not? Is there a technical reason why it's not possible or is that simply not done yet because nobody found the time to do it?)
