I've 10 days left on my premium Dashlane licence. I'm starting the evaluation of Enpass and might switch usong the actual premium price promotion https://www.enpass.io/pricing/ I've installed Enpass on my iPhone and Mac Book Pro. The migration of some 250 registration from my Dashmane ti enpass went allright in a few seconds. The sync is working with vault installed on Dropbox. Since my trust in the Cloud storage is limited, I prefer to have my vault stored on my own Synology NAS storage organization. I've not seen this possiility in the sync option. Is it possible ? My second question : is it possible to open a website double cliking on an Enpass registration url? It does not work when I do it. Many thanks in advance for your help and experience sharing. Kind regards.
