Why this trend, why now
Auth is the layer every B2B SaaS startup buys (rather than builds) in 2026. The winning providers in this cycle have shipped React/Vue/Svelte components that make 'add SSO in 10 minutes' actually work. Engineering signals here cluster on TypeScript SDK breadth and component-library commit cadence.
What to watch next
AI-agent authentication is the next frontier. Watch the providers that ship support for OAuth scopes designed for AI agents (delegated access, time-bound permissions, audit logs designed for LLM-generated requests). The first auth provider to make agent auth as easy as user auth wins the next category cycle.
