i am on Kubuntu 22.04 running KDE Plasma 5.24.7.
I have recently changed my Operating System user password, and I also changed my KWallet password.
Since then, when I boot my pc, this popup appears, sayng that
An application wants access to the keyring "Default keyring"

To unlock it I must enter my old kwallet password.
I am very confused:
- is this popup kwallet? I don't think cause I am totally sure that I successfully changed kwallet password
- how do I change this "Default keyring" password?
I have found this similar question but it's more focused on Gnome. I would also appreciate a clarification about the relation between kwallet and this keyring.
