I have signed up for business development coaching with 'save the high street'
They have come up with many useful ideas, but are wanting access to my business data .... - so (they say) they can
"open the possibility of more detailed and unique insights. It also allows us to track some of the impact of the things we're testing."

It means giving admin rights to Facebook / Google analytics etc - which just seems wrong ....

They say:
"The access to these accounts is being shared via mechanisms designed by Facebook and Google, so no sensitive information like passwords are being openly shared and you can revoke access at any time."

But it might be ... that they could revoke my access to these accounts ....

It's some kind of beta test, - so I have no basis to either trust or mistrust the consultancy offering this 'service'

Any thoughts?
