Auth::login($user) not working with ajax?

Question

Laravel

$user = User::create([
            'name' => $request->name,
            'email' => $request->email,
            'password' => Hash::make($password),
            'api_token' => Str::random(60),
        ]);

        Auth::login($user);

I made an Ajax request for the route with the same code, returned OK, but did not authorize.
POST request, if
so it won't work? it is necessary that the normal request was?
