> But then there's the fact that I don't trust Google with my user data and that I fear that at any time they could start charging onerous amounts for the service, or worse.
What, Google would never do that :)
But seriously, I think that developer focused solutions are safer than other products, especially if they are tied to revenue and are fully established.
A quick scan of https://killedbygoogle.com/ shows a few dev focused products, but more consumer focused ones.
Firebase auth itself is mostly free though - only phone-verified authentications are paid. I don't think they'd kill it but I wouldn't be surprised if they started charging on par with Auth0.
And if they're not charging for it, then what is the product? I mean, I know that they charge for other parts of the Firebase stack, but why offer a best-in-class authentication solution mostly for free?
