Troubleshooting Laravel Passport: Fixing Short Tokens and Authentication Issues

When working with Laravel Passport for API authentication, many developers encounter a common issue: receiving short tokens that do not authenticate properly, often redirecting requests back to the login page. In this guide, we will explore the root of this problem, and provide a detailed solution to ensure your API operates smoothly.

The Issue: Short Tokens

The problem statement can be summed up as follows:

Short Tokens: Upon attempting to generate an access token using Laravel Passport, the returned token is unexpectedly short.

Authentication Failures: These short tokens result in failed API requests, with responses redirecting to the login page instead of granting access to secured resources.

Initial Implementation Review

To understand why this problem arises, let's review the initial setup of Laravel Passport in your application:

Composer Installation: You have correctly installed Passport and performed the necessary migrations.

API Routes: Routes have been defined for handling login and protected resources.

Environmental Configurations: The .env file is set up with the required public and private key variables.

Despite these configurations, the issue arises because of a specific code implementation, particularly within the User model.

The Solution: Adjusting the User Model

Laravel now includes a use HasApiTokens statement in the User model by default, but it defaults to using Sanctum instead of Passport. This discrepancy causes the short tokens issue.

Steps to Resolve

Here’s how to fix the problem step-by-step:

Locate the User Model: Find the User class in your application (typically located in App\Models\User.php).

Update the Use Statement: Change the import statement from Laravel\Sanctum\HasApiTokens to Laravel\Passport\HasApiTokens.

Here's what you need to do:

Full Circle Testing: With the adjustments made, test to ensure that the token received is now a valid Passport token and that API calls can be authenticated appropriately.

Key Code Snippets

Here’s a summary of the essential configurations that should be touched:

Conclusion

By ensuring that your User model effectively leverages Laravel Passport’s APIs instead of Sanctum, you can resolve the short token issue and restore the functionality of your API authentication. With these straightforward adjustments, your application can seamlessly protect and manage user sessions as intended.
