Can only login with qq mobile!

I cannot login the Mac qq. It always says”mobile protection enable…”. However when I turn to my mobile qq, the mobile qq app says you have to update the app. OK, now I update my mobile qq in iPhone 6, the app crashs and I cannot use it any more since then. This is the most stupid app design I’ve ever used! It’s a pure joke!
