I want to create a browser extension that reproduce the Stack Overflow navbar (inbox and achievements):
I need for that to authenticate the current user using the authentication API.
For this step, I need to provide a
redirect_uri parameter that must be under an app's registered domain. It is used to redirected the user when he/she logged in.
My issue is that browser extensions don't have a URL (it's just like a local web application). So how can I log a user in a browser extension using the API?
