Laravel Sanctum vs Passport: Which API Auth to Pick

By Kokil Thapa | Last reviewed: August 2026

Choosing between Laravel Sanctum vs Passport: Which API Auth to Pick is often the first architectural decision you make when building a new backend. The wrong choice leads to unnecessary complexity or security gaps later. If you are starting a fresh project today, understanding the specific trade-offs prevents costly refactors down the line. This guide breaks down exactly when to use each package based on real-world implementation patterns.

Making this decision correctly early saves significant time. I recently outlined broader backend strategies in my article on Laravel API best practices, where authentication choice is foundational. Getting this wrong means either wrestling with OAuth2 flows for a simple mobile app or hitting a feature wall when your SaaS needs third-party integrations. Let’s look at how these packages actually function in production.

How does Laravel Sanctum handle API authentication?

Sanctum provides a straightforward authentication system for SPAs, mobile applications, and simple token-based APIs. It solves two distinct problems with minimal configuration overhead. In my experience shipping legal-tech portals and eCommerce platforms, Sanctum covers about 90% of use cases without the weight of a full OAuth2 server.

SPA Authentication via Session Cookies

For single-page applications living on the same top-level domain as your API, Sanctum uses standard Laravel session cookies. You do not manage tokens manually. The frontend makes a request to /sanctum/csrf-cookie to initialize CSRF protection, then authenticates via /login. Subsequent requests carry the session cookie automatically. This is identical to traditional server-side auth but works seamlessly with Vue, React, or Alpine.js frontends.

// Example: Axios setup for SPA authentication axios.defaults.withCredentials = true; axios.defaults.withXSRFToken = true; // Initialize CSRF + Login flow await axios.get('/sanctum/csrf-cookie'); await axios.post('/login', { email, password }); // Protected route works automatically const user = await axios.get('/api/user');

API Token Authentication for Mobile & Third Parties

When cookies won’t work (mobile apps, external services), Sanctum issues plain bearer tokens stored in a personal_access_tokens table. These tokens have no expiration by default—you control lifecycle through ability flags or manual revocation. Unlike JWTs, they are opaque strings validated against the database on every request. This eliminates token refresh complexity and makes revocation instant.

On a recent Nepal Gift Card platform build, we used Sanctum tokens for the mobile app while the admin panel used session auth. The unified middleware meant controllers didn’t care which method authenticated the user. This simplicity is why Sanctum is now the default recommendation for most Laravel API work.

When should you choose Laravel Passport over Sanctum?

Passport implements a complete OAuth2 authorization server. This is powerful but comes with operational cost. You should only choose Passport when your requirements explicitly demand OAuth2 protocol features. On legal-tech platforms like Court Marriage In Nepal, we’ve never needed Passport because clients authenticate directly—there’s no ecosystem of third-party apps requesting delegated access.

OAuth2 Authorization Code Grant

If users need to authorize third-party applications to act on their behalf (think "Login with YourApp" or granting a reporting tool access to their data), Passport handles the authorization code flow natively. Sanctum cannot do this. This pattern requires consent screens, redirect URIs, and code exchange—the full OAuth2 dance.

Client Credentials for Machine-to-Machine

When external systems need to access your API without a user context (inventory sync, webhook processors, partner integrations), Passport’s client credentials grant provides scoped access tied to a client rather than a user. Sanctum tokens always belong to a user model. If your architecture requires non-user actors with granular permissions, Passport fits.

Short-Lived Access Tokens with Refresh

Passport issues JWT access tokens with configurable expiration plus refresh tokens for renewal. This adds complexity (token rotation, refresh logic on clients) but enables stateless validation and automatic expiry. Sanctum tokens are long-lived by design. For high-security financial or healthcare APIs where mandatory token rotation is a compliance requirement, Passport’s built-in lifecycle management may be necessary.

What are the key differences between Laravel Sanctum and Passport?

Understanding the concrete trade-offs helps avoid misalignment. This comparison reflects actual production behavior in 2026, not theoretical feature lists.

The database load difference matters at scale. Sanctum validates every token against MySQL or PostgreSQL. At thousands of requests per second, this becomes a bottleneck requiring Redis caching or read replicas. Passport’s JWT validation happens in-memory using public keys—no database hit. However, for most Nepal-based projects serving regional traffic, Sanctum’s DB lookup is perfectly adequate and far simpler to debug.

How do you implement Laravel Sanctum in a production application?

Implementation is deliberately minimal. On Laravel 12.x with PHP 8.2+, Sanctum ships pre-configured. Here’s the actual workflow I use on client projects, stripped of documentation fluff.

Installation and Migration

Sanctum is included by default in new Laravel installations. If upgrading or working with an older skeleton:

composer require laravel/sanctum php artisan vendor:publish --provider="Laravel\Sanctum\SanctumServiceProvider" php artisan migrate

This creates the personal_access_tokens table. No encryption keys, no OAuth clients, no configuration files to edit unless you want to customize token abilities or expiration.

Issuing Tokens for Mobile Clients

Create tokens via the HasApiTokens trait on your User model. Always specify abilities for least-privilege access:

// In authentication controller $token = $user->createToken( name: 'mobile-app', abilities: ['orders:read', 'profile:update'], expiresAt: now()->addYear() // Optional explicit expiry ); return response()->json([ 'token' => $token->plainTextToken, 'abilities' => $token->accessToken->abilities, ]);

The plainTextToken is shown once. Store it securely on the client. All subsequent requests validate against the hashed value in your database.

Protecting Routes and Checking Abilities

Apply the auth:sanctum middleware globally or per-route. Check abilities inline when needed:

// routes/api.php Route::middleware('auth:sanctum')->group(function () { Route::get('/user', fn (Request $request) => $request->user()); Route::get('/orders', function (Request $request) { if (! $request->user()->tokenCan('orders:read')) { abort(403, 'Insufficient permissions'); } return Order::where('user_id', $request->user()->id)->get(); }); });

This pattern keeps authorization logic explicit and auditable. For complex permission matrices, combine Sanctum with Spatie Laravel Permission rather than overloading token abilities.

What are common mistakes when implementing API authentication?

After debugging numerous inherited projects, certain anti-patterns appear repeatedly. Avoiding these saves days of troubleshooting.

• Using Passport for simple mobile apps: The OAuth2 password grant was deprecated for good reason. If your mobile app owns user credentials directly, Sanctum tokens are safer and simpler. Passport adds attack surface without benefit here.
• Never expiring Sanctum tokens without a strategy: Default Sanctum tokens live forever. Implement either explicit expiration on creation, periodic rotation via background jobs, or user-initiated token management UI. Forever-tokens are a security liability on lost devices.
• Storing tokens in localStorage: For SPAs, rely on Sanctum’s session cookie mode instead. If you must use tokens (hybrid apps), store them in httpOnly cookies or secure native storage—never accessible JavaScript variables.
• Skipping ability checks: Issuing tokens with wildcard ['*'] abilities defeats the purpose. Define granular scopes matching your actual API surface. Audit token usage periodically and revoke unused ones.
• Ignoring CORS configuration: Sanctum’s SPA auth requires precise CORS setup. The config/cors.php paths must include /sanctum/csrf-cookie and your API prefix. Misconfigured CORS is the #1 cause of "works locally, fails in production" Sanctum issues.
• Forgetting to hash tokens in custom implementations: Never roll your own token storage. Sanctum hashes tokens before persisting. If you extend or replace this, ensure equivalent hashing. Plaintext tokens in databases are a critical vulnerability.

Which authentication package scales better for growing applications?

Scalability isn’t just about raw throughput—it’s about operational complexity as your team and user base grow. Both packages scale, but differently.

Sanctum’s database dependency becomes relevant around 5,000–10,000 concurrent authenticated requests per second. At that point, add Redis caching for token lookups or move to read replicas. For most Nepal-focused applications serving domestic and diaspora users, you’ll hit business scaling challenges long before Sanctum’s DB lookup becomes the bottleneck. I’ve run Sanctum on legal-tech portals handling thousands of daily document submissions without performance issues.

Passport scales horizontally without database coordination for validation, making it theoretically superior for massive multi-region deployments. However, the operational overhead of managing OAuth2 clients, key rotation, and token blacklists adds cognitive load. Every developer joining your team must understand OAuth2 flows. Debugging token issues requires tracing through multiple abstraction layers.

For teams building SaaS products targeting global markets with third-party integration ecosystems, Passport’s complexity pays off. For everything else—including most eCommerce, booking systems, internal tools, and direct-consumer APIs—Sanctum’s simplicity compounds into faster iteration and fewer production incidents. Start with Sanctum. Migrate to Passport only when you hit a concrete requirement Sanctum cannot fulfill, not because you anticipate needing OAuth2 someday.
