Hi Casper,
Thanks for the post! Are you referring to individual sites within a WordPress multi-site environment?
If so, RapID currently treats each individual site as an independent site, rather than having a combined authenticator across all the sites. This is because many multisites are collections that are administered by one person, but are otherwise independent. Granting a subscriber to one site doesn’t necessarily imply that they have rights on any other sites, as the WP accounts and anonymous IDs are not shared between sites. For that reason, a separate credential is needed for each site.

If you mean something different though, please could you explain a little more so that I can understand the issue properly?

Many thanks
