Hmm, when I bring up a new AlbyHub v1.8 it still asks me to connect my Alby account during the onboarding to get the Authorization code..
(and yes, I tried deleting ~/.local/share/albyhub)
hmm. it says 1.8.0 in the UI for you? during the onboarding you should be prompted about the account and also in settings you can now disconnect.
btw. 1.9.0 was just shipped.
