First of all I would like to say that your published articles are great.

I am implementing a very similar solution to your example. The problem is that when I use 'authenticated' :

REVOKE EXECUTE ON FUNCTION verify\_user\_password of anon, authenticated;

it denies me access when I call it from the Edge function.

If I just revoke "anon" it works.

How do you get it to work if you also revoke "authenticated"?
