Laravel Sanctum is a package that provides a simple and secure way to authenticate single-page applications (SPAs), mobile applications, and simple, token-based APIs. It allows each user of your application to generate multiple API tokens for their account, which can be used to access protected resources without having to log in every time. It also allows you to authenticate SPAs using Laravel’s built-in cookie-based session authentication, which provides CSRF protection and prevents XSS attacks Laravel Sanctum is considered to be a secure authentication system, as it uses Laravel’s encryption services to encrypt and decrypt the API tokens, and uses a message authentication code (MAC) to verify the integrity of the tokens. It also prevents SQL injection attacks by using PDO and parameter binding, and protects against cross-site request forgery (CSRF) attacks by using a CSRF token for each active user session However, using Laravel Sanctum does not guarantee that your application will be secure by itself. You still need to follow some best practices and security measures to protect your application and data, such as:
Use HTTPS: You should always use HTTPS for your application, especially when sending or receiving sensitive data, such as API tokens or user credentials. HTTPS encrypts the communication between the client and the server, and prevents man-in-the-middle attacks, eavesdropping, or tampering
