Authentication
4 components · sorted by setup time
The setup killer. Get this right in the first 30 minutes.
Why it matters
Every hackathon project that needs user accounts lives or dies on auth. Wrong choice means hours of debugging OAuth redirects at 2am instead of building features. The good news: modern auth providers handle the hard parts for you — Google sign-in, session management, email magic links — in under 30 minutes if you pick the right tool.
⚠ common pitfall
Don't roll your own. Don't start with email+password unless it's core to your concept. Don't use two auth providers. Pick one and commit.
✦ how to choose
Supabase Auth if you're already using Supabase. Clerk if you want the fastest drop-in with the best UI out of the box. NextAuth if you're deep in the Next.js ecosystem and want full control.
