The HMRC have already indicated the direction they would like to go, this includes the new software being able to automatically send out invite requests to new clients to automatically grant authorisations, etc
To this end, it is expected that when the AGENT connects, transmits of receives information from the government gateway that your personal credentials are used and not that of the Clients.
We have already included this feature into the system, and as soon as the HMRC request that it is implemented it will work.
