-- Lists the MFA devices for an IAM user. If the request includes a IAM user name, then this action lists all the MFA devices associated with the specified user. If you do not specify a user name, IAM determines the user name implicitly based on the AWS access key ID signing the request for this API.
--
-- You can paginate the results using the 'MaxItems' and 'Marker' parameters.
--
-- This operation returns paginated results.
