如果你使用预期的功能，那么在Breeze的routes中使用web.php和api.php，一切都会很好。当你用api登录用户时，也会设置会话cookie，反之亦然。我已经离开breeze一段时间了，它不像JetStream那样使用Sanctum吗？

Middlewares = [
    'auth:sanctum',
    config('jetstream.auth_session'),//which is AuthenticateSession::class
   ]

你可以在config/auth.php中为web和API返回设置不同的保护[

/*
|--------------------------------------------------------------------------
| Authentication Defaults
|--------------------------------------------------------------------------
|
| This option controls the default authentication "guard" and password
| reset options for your application. You may change these defaults
| as required, but they're a perfect start for most applications.
|
*/

'defaults' => [
    'guard' => 'web',
    'passwords' => 'users',
],

/*
|--------------------------------------------------------------------------
| Authentication Guards
|--------------------------------------------------------------------------
|
| Next, you may define every authentication guard for your application.
| Of course, a great default configuration has been defined for you
| here which uses session storage and the Eloquent user provider.
|
| All authentication drivers have a user provider. This defines how the
| users are actually retrieved out of your database or other storage
| mechanisms used by this application to persist your user's data.
|
| Supported: "session"
|
*/

'guards' => [
    'web' => [
        'driver' => 'session',
        'provider' => 'users',
    ],
   
],

在config/sancup中，您可以将Web gaurd定义为默认值：

'guard' => ['web'],

这应该都已经为你设置好了！然后你就可以使用web.php中的中间件来处理使用sancum的web，而routes/api.php应该被用于路由，也就是你定义授权路由的地方：
//routes/web.php路由：：中间件（[ 'auth：sancum'，]）-〉组（函数（）{

//protected routes
   

});


//api.php
Route::middleware('auth:sanctum')->get('/user', function (Request $request) {
    return $request->user();
});

breze已经在web.php中创建了这个，它的工作非常简单，我想不出如果你做得对，需要手动设置什么，我认为你只需要使用路径separate和使用middlewears，并按照laravel安装文档安装sancutum和breeze with breeze。
