Intra-computer Metasys system local accounts are used to perform authentication and authorization among devices within the Metasys system. An intra-computer account is a Metasys system site account, which means the account resides in the same proprietary user store as the other Metasys users. The intra-computer account cannot be administered and cannot be used to log in to the system through the Site Management Portal UI. The intra-computer account uses a generated password that is programmatically changed once a day. Active Directory service accounts are not used for intra-computer accounts.
