is Jwt token was UNIQUE

Question

I'm using JWT web token system. I was able to generate TOKENS successfully. I'm creating JWT tokens in Laravel as follows

I'M USING FOLLOWING TECHNOLOGY STACK

• LARAVEL 5.2 framework
• JWT (package)

SAMPLE CODE

use JWTAuth;
use Tymon\JWTAuth\Exceptions\JWTException;

class AuthenticateController extends Controller
{
    public function authenticate(Request $request)
    {
        // grab credentials from the request
        $credentials = $request->only('email', 'password');

        try {
            // attempt to verify the credentials and create a token for the user
            if (! $token = JWTAuth::attempt($credentials)) {
                return response()->json(['error' => 'invalid_credentials'], 401);
            }
        } catch (JWTException $e) {
            // something went wrong whilst attempting to encode the token
            return response()->json(['error' => 'could_not_create_token'], 500);
        }

        // all good so return the token
        return response()->json(compact('token'));
    }
}

QUESTION 1

Is the generated token is UNIQUE?

Answer 1

JWT is unique in a way that no two same users can have the same token generated for them
