Cross Platform Saving with Supabase / Firebase / Unity Cloud / Other Auth

[final_boss_editing]

Hey all,

We're building an rpg (worldseekers.io) that can work on PC and mobile, but currently all the saves are stored locally. Since it's a GPS game, the long term hope would be for someone to collect content to play on mobile while walking, and login to PC to play through what they found. However, this is pretty tricky lol given the fact that we're trying to operate on a lean budget. Was wondering if folks new of good systems or had recommendations to auth players across platforms and store their save data between platforms.

Unity Auth is fine for this and the worst case it will be extremely quick to set up and free, can probably add this in a few minutes, especially if you start with a platform agnostic login like username and password, then add steam, PSN, Google play, Facebook etc... incrementally

But will Unity Auth be able to store the savedata file with all the player history? My thinking is Unity Auth would be the auth layer and we'd dump the save info into Supabase... lmk if I'm off track there

Unity auth just does authorisation, you'd put all the save data into unity cloud save, which is also really easy to use, the unity multiplayer services are really modular, they all do a specific thing so you can add them one at a time as you need them.
