At Magenta Cloud I generated a vault and released the related folder so that a friend could access it. A password nor an Magenta Clound account is needed to access the data (in general).
Unfortunately, when I open the iOS Cryptomator to add a WEBDAV based folder (by entering the related url), the app keeps asking me for a WEBDAV userID and a password …
Both is not needed (and will not be provided) when releasing/accessing the released Magenta folder …
That is what I did anyways.
But the point is: By knowing this very password, one has access to all date of that WebDav … not just to the files I released to a friend.
Example: I release the folder /blablabla/myfriend. My friend would have access up to the root directory, not just to the subdirectory of /blablabla/myfriend.
So your friend can’t just create his own MagentaCLOUD account and you both access the same data. MagentaCLOUD can only create public links.
That’s why I can’t give you any solution other than suggesting to use another cloud storage service that supports sharing functionality so that everyone has its own account.
