-- Lists the MFA devices for an IAM user. If the request includes a IAM
-- user name, then this operation 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 Amazon Web Services access key ID
-- signing the request for this operation.
--
-- You can paginate the results using the @MaxItems@ and @Marker@
-- parameters.
--
-- This operation returns paginated results.
