Hello Trey Greer,
thank you for your response .
I read the documentation that you put me in link but unfortunately that does not suit me since with such a solution I will be obliged to run a machine 24 hours a day to host the server.
Today the only machine that runs 24 hours a day at my home is a Synology NAS synced with Dropbox and which hosts my current password manager file.
The only problem is that I think this password manager is not very well maintained …
If one day you decide to give us the possibility to choose the location of the file, do not hesitate to let me know.
Stéphan
