Using Alexa to Disarm alarm

Just wondering about the safety/security of using Amazon Alexa to arm/disarm alarm system.As far as am aware Alexa stores commands given to it in the cloud and is looked at by real people sometimes .So when arm/disarm alarm believe have to give your alarm code, if so then isn't this a security issue as if stored in cloud so possible some employee or someone could find code.Or am I just being overly paranoid ?
