worker-auth-providers

worker-auth-providers is an open-source library providing authentication providers for Cloudflare Workers. The current version is 0.0.14-beta.10, released as a beta with irregular cadence. It supports OAuth and OTP authentication for providers like GitHub, Google, Facebook, Discord, Spotify, Twilio, Mailgun, SendGrid, and AWS SNS. Designed specifically for Cloudflare Workers, it is lightweight with minimal dependencies. Key differentiators vs. alternatives like Auth0 or Passport.js: it runs at the edge with no external server, is framework-agnostic, and uses KV storage for OTPs. Types included.
