Are there any OpenAI authorization servers that applications can point users to?

The OpenAI API is exciting and I eagerly await the plugins. For the applications developed that make calls to the OpenAI API, is there a way that I can redirect the users through some OpenAI authorization server that performs the OAuth credentials check? I want them to be able to use my app on their own OpenAI account. Here, an OpenAI maintained authorization server would be much safer than setting up my own authorization server to manage the user’s API keys.
