Google Analytics measurement protocol authentication?

Question

I'm looking at Googles Measurement Protocol, which gives you a way to send google analytics information from your server. However, there doesn't seem to be any authentication required. Have I missed something? Otherwise, what's to stop other people randomly spamming fake data to my account?

Answer 1

There is no authentication required. There is nothing to stop people randomly spamming your account.

This is what has lead to the 'Ghost Referral' issue. See Link: https://moz.com/blog/stop-ghost-spam-in-google-analytics-with-one-filter

Google Analytics was initially set up the measurement protocol with good will envisaged, however this has not been the case.
