Auth debt compounds silently.
Weak auth is the #1 attack vector in data breaches, and the longer it sits unfixed, the higher the risk. One compromised credential can expose customer data, trigger compliance violations, and cost months of engineering time to recover from.

CREDIBILITY
After building auth at companies like SoundCloud, I've seen the patterns that work — and the shortcuts that create months of rework later.
You don't need enterprise-grade complexity right now. You need solid foundations that grow with you — without becoming the bottleneck.
