I will be presenting next week at this year’s EuroPython (virtual conference). While not specifically in Sanic, I will be using it heavily in my talk. If anyone is going to be attending, I’d love for you to join the talk and let me know your thoughts afterwards.

Will there be a video back then? Can you send it out and let us study it too 
Absolutely. I think the official video will be available from EuroPython in a few weeks after the event.
Slides and examples will be made available here: https://github.com/ahopkins/europython2020-overcoming-access-control
Thank you for your speech on EuropePython. It was really wonderful. Although I didn’t see the video, I saw your PowerPoint and sample code. I feel it very good. In addition, I would like to ask how to realize OIDC. I happened to be studying OAuth2 recently, but I found that it can only be authorized, but not authenticated. And I can’t find an easy-to-use OAuth2 library. Do you have any good suggestions?
Thank you very much.
Have you looked into sanic-jwt. It is pretty simple to setup an oauth flow if you need it. And, it with a couple function definitions to tell it where to get user info, it will setup a /auth/me endpoint to provide identity.
Are you trying to setup an oauth/openid server, or connect to one?
Wow! Great presentation there!
BTW, sanic-jwt has a simple permission system? That is wonderful! I am working on a simple permission tool either, maybe I can learn from it. 
Thanks 
Yes, there is a permission scoping mechanism built it: https://sanic-jwt.readthedocs.io/en/latest/pages/scoped.html
Good luck. If you need any help let me know.
Also, here is a slightly heavier featured standalone version: https://ahopkins.github.io/structured-scopes/
