Handle more than one nextcloud with one privacyidea?

is it possible to handle multiple nextclouds with one privacyIdea installation?
Thanks a lot!

Yes of course it is possible.
Just like you can connect many different applications to authenticate against privacyIDEA.
After all, this is the sense of a central two factor authentication system.

It is easier to also have one central user store. However, you can also connect many different userstores to privacyIDEA.
