Top reviewed authentication & identity tools

Top reviewed

"Across this list, teams choose between all-in-one app backends, developer-first auth layers, and enterprise identity depth. Firebase suits apps needing login alongside realtime data and messaging, while Clerk emphasizes polished drop-in flows, session control, and org management for modern SaaS. Auth0 remains the stronger fit for complex SSO, federation, provisioning, and fine-grained access needs."

MonoCloud for Startups

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.

What's something you wish your ID could do?

Hey there, Manuel from Nomadful here. In preparation for our upcoming launch, I wanted to open up the conversation with this simple question, all ideas welcome! I'll start with a couple of things I wish my ID could do/have:

Personalisation: It's 2025, and it's hard to think of a future where personalisation isn't key. What if I could control what I want my ID to show based on the current situation. (For example, if I need to confirm my age to access a concert venue, do I really want security staff checking on my address or nationality?)
Universal usage: Why can't we just use one ID for multiple things? Wouldn't it be useful to have some utility help you login or autofill data online based on that same ID?
Privacy: What if IDs could really be bulletproof, and never leave your phone? If stolen, that sensitive data would be gone so no one could use it against you. (Although we would still need some kind of physical copy for backups).

While I can't just yet reveal the final product, I can assure you we're building something towards these goals: a privacy-focused, digital medical ID that will definitely change the health industry for years. But we're also scaling these product to developers, restaurants and venues, to make a comprehensive authentication system.
What's your take on this?
