I have an Android application that uses Google APIs (Drive API, Drive SDK, G+ API) which is currently working properly.
Within the Google Developer Console I originally created two 'Client ID' OAuth Credentials one for production and one for debug/development. I recently logged in and noticed there are now 17 Client IDs. 16 of which use the same SHA1 value used for my production/published instance (the Client ID values are all different.)
How and why were the other 15 Client IDs created (I am the only developer with access)? Can I delete some of these.. if so which ones? And finally what 'tag' on SO represents the Google Developers Console?
