-## Multiple security schemes
-
-If you would like to define multiple security schemes, simply 
-list them under `components.securitySchemes`. For example, if you wanted to support 
-`basic` and `apiKey` security schemes, see the example below: 
-
-```yaml title="openapi.yml" {3,6}
-components: 
-  securitySchemes: 
-    BearerAuth:
-      type: http
-      scheme: bearer  
-    ApiKey: 
-      type: apiKey
-      in: header
-      name: X_API_KEY   
-```

 ## Override security scheme
 
 You can use `generators.yml` to define custom authentication schemes that will take precedence when generating SDKs. This is also how OAuth authentication is configured for OpenAPI specs.
