Do Android third-party applications have to pay for WeChat login authorization, and can they use Wechat Official Account’s developer qualification?

  android, question

For example, an Android project is currently being developed to realize WeChat’s authorized login function. However, referring to wechat open Platform, after registration, there is no authorized login function by default, which requires certification qualification, i.e. payment. However, I have been certified by Wechat Official Account before and paid the fee. Can Wechat Official Account be associated with the open platform? Aren’t they all WeChat? Why can’t they be related? It feels so bad!

These are two different concepts. Authorized login is for project application, and Wechat Official Account is Wechat Official Account. Wechat Official Account does not have application login function. Of course, there is no authorized link between the two.
