Where can I set the client access type (as confidential) in the keyclock 20.0.3 ? I am not able to find a option to set the access type.
When creating a client, there is no option also after creation, in the settings menu there's no access type option.
I have attached a screenshot for the same.
In the same page as in your screenshot you should have an option to toggle Client authentication
, once it's on the client should be confidential. The tooltip for it is:
This defines the type of the OIDC client. When it's ON, the OIDC type is set to confidential access type. When it's OFF, it is set to public access type
