What's the common GCP service to receive custom user events from mobile and web client

Question

I'm trying to build a data architecture on GCP. I want pubsub to receive mobile and web browser client events and then send it to dataflow and from there to bigquery. But what service should handle authentication? Otherwise anyone can send me any events, isn't it? What's the common / best practice here?

From what I recall, the firebase family of products is aimed at solving this type of problem https://firebase.google.com
