Best way to send data between places securely

Hello! I am making a game where i need to send data between two universes. I have been thinking about sending the data with the teleport when the player teleports to the place. But this has to be secure.

What is the best way of doing this?

The documentation for teleportData recommends using DataStoreService for “secure data” as you mentioned. Though, I also recommend looking at MemoryStore if it’s applicable for use.

Is memory store saved across different universes?

(If i wrote places in the post i mean universes)
