"If you are using multiple vaults, then each vault need to be synchronized with a separate cloud account."
I take it the enpass engineers built and tested the multiple vaults feature among themselves to combine professional and personal vaults, but they didn't seem to think about family sharing among just personal accounts. This limitation means I can't use multiple vaults to share passwords with my wife. We need to be able to sync our personal vaults and a single shared vault through our existing personal OneDrive accounts.
If we use the folder sync feature as an alternative to let the cloud service sync the vaults in the background (not through enpass), then what will prevent sync conflicts that we have to resolve manually in the OneDrive web UI (and losing 1 person's most recent password updates)?
