I found a similar thread here but that is for .Net Core. I have the same issue with Swagger.Net API(.Net Framework).
I am using Swagger.Net API version 8.3.35.101 with .Net framework 4.6.1 and I am getting a lock icon for each and every method in the Swagger UI. Some of the API's in my application doesn't need authentication, therefore I want to remove the padlock icon from such API's.
The padlock icon which needs to be removed can be seen in the above image highlighted in red. I believe hiding it for Anonymous methods can be achieved by implementing IOperationFilter but couldn't find any sample code to achieve it with .Net framework.
Here is the answer from what we discussed in the comments:
The issues is the incorrect type on the config of ApiKey
here is how it should be:
c.ApiKey("apiKey", "header", "API Key Authentication", typeof(KeyAuthorizeAttribute));
c.ApiKey("appId", "header", "APP ID Authentication", typeof(KeyAuthorizeAttribute));
That code on github:
