You can create and register an OAuth App under your personal account or under any organization you have administrative access to. While creating your OAuth app, remember to protect your privacy by only using information you consider public.
You can enable other users to authorize your OAuth App.
Scopes let you specify exactly what type of access you need. Scopes limit access for OAuth tokens. They do not grant any additional permission beyond that which the user already has.
You can replace the default badge on your OAuth App by uploading your own logo image and customizing the background.
