The present disclosure provides generally for system and method of authenticating a source of electronic communication. According to the present disclosure, authenticable communications may allow for authentication of a source of the electronic communication, which may limit potential damage caused by fraudulent communications. In some aspects, an authenticable communication may allow the recipient to confirm that the indicated source is the actual source of the authenticable communication. In some embodiments, the authentication may not require an exchange of encrypted communications or an exchange of communications solely within the same communication system. Authenticable communications may provide a separate layer of security that may allow a recipient to review the contents with confidence that the communication is not fraudulent. Further, authenticable communications may provide the additional security without requiring specialized software.
