Taildrop if you use Tailscale.
<offtopic> It’d be nice if there’s a Syncthing built into Tailscale or some of the mesh VPN solutions. Taildrop is good but it’s not entire directory sync with proper conflict resolution.
Surely I can use Syncthing inside Tailscale but 1. I have to depend on their public discoservers, or 2. I have to host and configure the discoserv myself for every client which is tedious to do </offtopic>

Support for delegation to an external IDP (without MAS) is a work-in-progress
