+Q: How to reset your authentication settings (and also fix some authentication errors)? 
+
+A: Delete the credentials file and re-authenticate. The credentials file is located at:
+
+> Windows: C:\Users\USER\.config\earthengine\credentials 
+> Linux: /home/USER/.config/earthengine/credentials 
+> MacOS: /Users/USER/.config/earthengine/credentials
+
+Q: I am still getting authentication errors, what should I do?
 
 A: Try installing the Google Earth Engine [command line client](https://developers.google.com/earth-engine/command_line). Run the `earthengine authenticate` command. This resets the authentication credentials and solves most authentication errors.
