## When it is useful

Add Descope login (OTP, magic link, passkeys, OAuth, SSO, MFA) — Next.js/React/backend router.

## The Catch

Vendor lock. False-fires on generic add-auth. Hosted <Descope> widget, not BYOS. Free Forever 7.5k MAU / 10 tenants / 3 SSO. SMS/voice via Descope connectors: 100/mo then sign-in breaks unless BYO. Distinct from Clerk/WorkOS.
