One player, every platform.
Cross-save, cross-progression, cross-platform inventory. Guest → OAuth → account merge, with one identity the whole platform respects. Every other module reads the same player ID.
Everything a multiplayer game actually needs to launch.
Guest-first onboarding
Players start playing instantly. Promote to a permanent account when they want to; no sign-up wall at the front door.
Account merge that audits
Link Steam, Apple, Google, PSN, Xbox, Nintendo. Merges are reversible, logged, and support handles them from a dashboard.
One ID across every module
Vault grants, Sync presence, Lens cohorts, Stage segments — all keyed to the same player identity.
Platform SDKs as first-class
PSN, Xbox Live, Nintendo Account, Steam, Apple — supported as providers, not left as a future ticket.
Cross-save by construction
Progression and inventory live in the runtime, not on the device. Switch platforms and continue mid-session.
GDPR / DMA-ready by default
Export, delete, and consent endpoints ship with the module. Regulatory asks become a dashboard, not a migration.
Passport fits three kinds of teams.
Ship cross-play without writing identity again
A single player ID the whole backend agrees on — so multiplayer, monetization, and analytics share context out of the box.
First-party requirements met from day one
PSN, Xbox, and Nintendo integrations live in the module. Cert submissions don't wait on a custom auth service.
Account merge that doesn't burn the weekend
When a player links a new platform mid-season, the merge is logged, reversible, and doesn't need a custom migration script.
Sample journeys through Passport.
Synthetic stories — the real customer names land here when their games do.
Passport is one module, used by every other.
Identity is cross-cutting: Sync needs it for presence, Vault for entitlements, Lens for cohorts, Stage for segments. One module, one player ID, every other PlayServ pillar reads from it.
Cross-platform continuity as a managed bundle.
- PlayFab covers auth + cloud saves, no first-class inventory merge
- EOS is viable and free but Epic-centric for entitlements
- Firebase Auth — no console providers, no cert templates
- AccelByte — enterprise cross-platform, heavy integration cost
- Cross-platform inventory merge bundled in
- Player-readable conflict-resolution UI
- Cert-pack templates for Sony TRC / Microsoft XR / Nintendo
- One ID respected by every PlayServ module
The cert team still owns submission; we compress the prep work so first-party isn't a six-week milestone of its own.
Passport is included on every Platform tier.
Free up to 1,000 MAU. Studio ($299/mo) covers a cross-platform game; Pro ($799/mo) adds SAML/SCIM and advanced account-merge workflows for larger teams.
