No, this is not permitted. Sharing a user ID for REX is against REX Veterinary Software’s end user agreement. Also, by sharing a user ID and password, REX would be unable to accurately track records. Entries made in REX are specific to the user. For example, if two veterinarians share the same user ID, the controlled medication log entries would have no way of discerning who administered a controlled substance to a pet. Also, for legal reasons, REX has a built in audit tracking system that logs every entry and change made to the system by each user. Should the unfortunate circumstance occur that this data needed to be provided for a legal case, certain users could be implicated in the legal proceedings that would otherwise not be.
