Personally I use Zotero with my own WebDAV server for sync. Works as advertised, without a hitch.

Did you sync all data to multiple computers without a Zotero account? Zotero's documentation said WebDAV could sync attachment files. But everything else required a Zotero account.[1]

No you can't. I have both a Zotero account and a WebDAV server. Since bulk of the load is the attachments, doing it this way doesn't bother me, actually.

I do both. I have the Zotero account for the library and webdav for the pdf files.

The question was could all data be synced without a Zotero account.

My understanding then is the answer is “probably no.”
