-Supported schemes are basic authentication, an API key (either as a header or as a query parameter) and OAuth2's common flows (implicit, password, application and access code).

#### Security Requirement Object
Lists the required security schemes to execute this operation.
-The object can have multiple security schemes declared in it which are all required (that is, there is a logical AND between the schemes).
-
The name used for each property MUST correspond to a security scheme declared in the [Security Definitions](#securityDefinitionsObject).
+Security Requirement Objects that contain multiple schemes require that all schemes MUST be satisfied for a request to be authorized.
+This enables support for scenarios where there multiple query parameters or HTTP headers are required to convey security information.
