QML use C ++ function with parameters

I was using widgets in my application, but I am migrating to qml because of the appearance but I intend to continue using C ++ in the banckground

class Usuario : public QObject{

    Q_OBJECT

    Q_PROPERTY(bool login WRITE login)

public:

    Usuario(QObject *parent = nullptr);
    ~Usuario();

    static bool login(const QString& usuario, const QString& senha);

};

When compiling I get an error indicating that the function does not receive any arguments, so how can I call the login function in qml?

You are confusing concepts, Q_PROPERTY does not serve to expose functions or methods but to create a property (more information here), what you should use is Q_INVOKABLE or Q_SLOT:

class Usuario : public QObject{
    Q_OBJECT
public:
    Usuario(QObject *parent = nullptr);
    ~Usuario();
    Q_INVOKABLE static bool login(const QString& usuario, const QString& senha);
    // or
    // Q_SLOT static bool login(const QString& usuario, const QString& senha);
};
