This is what we need. We have a client portal that we want the client to be able to look at their Analytics account directly from this, so that they do not need to log into their Google Analytics directly. There is a Google Analytics API call that needs to be authorised and once thi sis done, they can then look at such things like: visitors, traffic sources, goals, events etc.
The website portal has a unique login for each client so once they are in, they need to be able to see their own unique Google Analytics account.
This is stage 1 of several, so it's an ongoing job, but this will do for a start.
