which RFC would that be

the current two webdav backends use FTP_PASSWORD, if it ss set.

make sure to url encode the @, the above is clearly breaking the standard eg. like

as said above, use FTP_PASSWORD. it works

try

FTP_PASSWORD='supersecretpass'
duplicity /source webdavs://user%40host.tld@xxxxxxxxxxxxxx/targetfolder

quotation marks or @ have no place in the url's auth info.

make sure you use a recent duplicity. either 0.6.26 or the latest 0.7.x
