Open, extensible, and built for real systems

Authentication, Authorization,
and Identity — Without the Guesswork

Auth Flow is a modular identity and access platform that helps teams design, operate, and evolve secure authentication and authorization systems—without locking into rigid workflows or proprietary abstractions.

Build identity your way. Scale it safely. Govern it clearly.

auth-flow.config.ts
// Configure your identity system
import { AuthFlow } from '@authflow/core'

export const auth = AuthFlow.init({
  providers: ['passkey', 'magic-link', 'oauth'],
  rbac: true,
  multiTenant: true
})
