@fastfinge There are people using the public clipman server right now, same token, different history passwords. The database buckets are of course not shared.
If you think of the server token like a key card to get into the building, then the history password like a combination lock on a room within that building. You share the same lock between clients, they can communicate.
If you have two clients that enter two different history passwords, no matter how loud you shout, no other client will hear you.
The manual did mention this but it wasn't clear, so have tried to make it more so.
