I'm going to use this https://github.com/wolfhund/falcon-oauth For now it just supports oauth2 wolfhund/falcon-oauth#35 and may have compatibility problems. I keep a fork and will make the necessary changes

The solution above didn't work well. Next check will be on https://github.com/wndhydrnt/python-oauth2 . Seems a mature project but another projects should be worth considering. This is something important and need to be careful reviewed
