I am having the same issue.
I recently reinstalled Enpass on one of my Macs and imported passwords from 1Password. No issues with that.
However, the problems began when I installed Enpass on a second Mac and went through the process of setting it up.
I selected it as being used for PERSONAL use. It then asked where my vault was stored which is iCloud. That worked fine on the first machine, but on the second, it told me I had to sign in with Enpass and when I did, I was sent to iCloud to rest my password (which I certainly don’t want to do)
Doesn’t Enpass store the vault somewhere within iCloud so that any Mac connected to that account will easily find it? That doesn’t seem to be the case here.
