MonoCloud for Startups

Are your backend services authenticated or just trusted by default?

most teams spend a lot of time thinking about user authentication. who can log in, how, with what credentials.

and then the services behind the scenes just... trust each other. because they're on the same network. because they're in the same VPC. because nobody questioned it when the architecture was first drawn up.

Your user signs in with Google today and Apple tomorrow. Is that one account or two?

I was thinking about this because it sounds like such a small product decision, but I don t think it actually is.

Someone signs up with Google. Six months later they are on their iPhone and tap Sign in with Apple. Same person, different identity provider. And if they use Hide My Email, you may not even get the same email address.

So what should the product do?

Creating a new account feels wrong because now their history, billing, settings, or subscription can end up split across two profiles. But automatically linking accounts based on email also feels risky, because now you are assuming that matching email addresses are enough proof that both identities belong to the same person. And then Apple makes it even messier because the emails may not match at all.

When did you actually start taking auth seriously?

A big part of my week is spent talking to early-stage founders about how they handle login, access, and identity, and there is a pattern I keep noticing that I want to understand better.

Almost everyone puts auth off at the start, which honestly makes sense when you are still trying to prove the product matters at all.

What auth provider are you using in your stack, and would you choose it again?

Curious what the community is running for authentication/authorization in their apps (e.g. Auth0, Supabase Auth, Clerk, Firebase Auth, Cognito, etc.)

A few things I'd love to hear your take on:

What provider are you using and what's your primary stack? (e.g. Next.js + Clerk, Go + Auth0, etc.)
What's the one thing that surprised you , good or bad ?
Would you make the same call today? Especially curious if you've hit scaling pain.

For context: I'm building a B2C application with my own database layer, and currently in the process of evaluating which authentication provider best fits the architecture. Trying to understand how others are handling the auth <> database relationship and what influenced your final decision.
