Passport Multiauth Laravel Package

Product Decisions This Supports

• Multi-persona authentication as a first-class capability. Laravel Passport ships with a single global user provider — one token table assumption, one User model. This package makes the OAuth guard/provider pair the unit of identity, so an app can issue and validate tokens for admins, customers, drivers, or partners independently. That unlocks a product decision most SaaS roadmaps eventually hit: do we model these as roles on one user table, or as genuinely separate identity domains?
• Build vs. buy for auth plumbing. The alternative to adopting this is 3–6 weeks of engineering to swap Passport's TokenRepository, ClientRepository, and personal-access-token factory for guard-aware versions — subtle, security-adjacent work with a long tail of edge cases (token refresh, revocation, scope leakage across guards). At 283 stars and MIT licensing, this is a cheap way to defer that spend and validate demand before committing.
• Roadmap sequencing for B2B / marketplace expansion. If the next two quarters include a partner portal, a seller console, or a separate mobile app for a different user class, this is the enabler. It lets the team ship a second identity surface without a parallel auth stack or an SSO migration.
• Segmentation and compliance posture. Separate providers give separate audit trails, separate token lifetimes, and cleaner blast radius — a customer token can't resolve to an admin principal by construction. That is a real answer to "how do you segregate privileged access?" in security reviews, not just a code convenience.
• Data-model decisions with downstream cost. Adopting this effectively ratifies "multiple user tables" over "one table plus a role column." That choice ripples into reporting, support tooling, and admin search. Making it explicitly here is cheaper than discovering it during a migration.
• Prioritization of auth work against everything else. A concrete, low-effort option raises the cost of not doing multi-persona auth this quarter, and gives you a defensible "we'll defer the identity refactor" line item with a named interim solution.

When to Consider This Package

Consider it when:

• You are on Laravel ≤ 8 with Passport ≤ 9 (roughly the 2019–2020 dependency window this package was built and last released against) and have a working Passport implementation you are extending, not replacing.
• You already maintain separate user tables — or have a firm product reason to — for distinct actor types that log in differently, have different profile schemas, and different lifecycles.
• The distinct identities need independent OAuth clients (first-party mobile app vs. partner integration) with client-scoped tokens.
• You can vendor the source or fork it and accept ownership of a ~1–2k line patch to Passport internals, including the upgrade tax on every Passport major.
• You are time-boxing a validation — a pilot, a design partner, a market test — where proving the multi-persona model matters more than long-term dependency hygiene.

Look elsewhere when:

• You are on Laravel 9/10/11/12 or Passport 11+. The last release was April 2020 and it has zero dependents in the ecosystem; it patches Passport's internals, so an unmaintained fork means you own the merge conflict on every Passport bump. A single GitHub-issue triage cycle should settle this before you write a line of code.
• A single users table with roles/permissions (Spatie, Bouncer, or Gates) actually models your domain. Multi-guard auth is a heavier hammer than most RBAC problems need, and it complicates joins and admin tooling permanently.
• Laravel Sanctum covers the requirement. If you don't need full OAuth2 authorization-code flow, client credentials, or third-party app consent, Sanctum is first-party, maintained, and simpler — this is usually the correct default for SPA + mobile first-party auth.
• You actually need a real identity provider — SSO/SAML, SCIM provisioning, MFA, social federation, per-tenant IdPs. That's Auth0, Keycloak, Cognito, or WorkOS, and no Laravel package substitutes for it. Decide this before adopting anything.
• The identity boundary is a security or compliance requirement with an audit obligation. Betting that on a 2020-era unmaintained dependency is a decision your security reviewer will push back on, correctly.

How to Pitch It (Stakeholders)

For executives — one paragraph: We need to serve a second class of user (partners / sellers / field staff) with their own login and their own tokens. Today our auth stack assumes one kind of user, and retrofitting it properly is several weeks of security-sensitive engineering. An open-source MIT-licensed package exists that closes most of that gap for roughly a day or two of integration. I recommend we use it as a bridge to validate demand this quarter, with an explicit ticket to replace or formally adopt it — not as a permanent foundation. The risk is not cost, it's staleness: the package hasn't been updated since 2020, so we should plan to own it.

For engineering — the ask: Spike it for two days against our current Passport version. If it installs cleanly and the guard-aware token flow passes our existing auth test suite plus three new cases (cross-guard token rejection, refresh under a non-default guard, revocation isolation), vendor it into the repo and treat it as our code. If the Passport version mismatch requires patching internals ourselves, we stop and re-scope — the build estimate stands at 3–6 weeks and we'd rather spend that deliberately than by accident.

The honest framing: This is a good decision for deferring cost and a bad decision for avoiding it. It buys us a quarter of validated learning on a new user segment at roughly 5% of the build cost — provided we accept that the dependency is frozen in time and budget the ownership accordingly. The signal to watch is simple: if the spike requires us to modify Passport internals ourselves, the package has already stopped paying for itself.
