Last couple of weeks I have been working on a new implementation of the login and security stuff in our new MVC application. We wanted to use 3 external OAuth Authentication providers (LinkedIn, Microsoft and Google). I noticed I had to look up application configuration links from samples and tutorials on the internet, since they were hard to find when actually logged on as a user for each of these services. So for easy reference, here are the URLs:

Microsoft: https://account.live.com/developers/applications/index
Google: https://console.developers.google.com/project
LinkedIn: https://www.linkedin.com/secure/developer

Another thing of note are the strange things you request from a user’s Google account when using OAuth. See for instance these stackoverflow questions: http://stackoverflow.com/questions/18329629/scope-to-get-email-address-alone
