What Sylphx Auth does

  • Every sign-in method

    Passkeys, magic links, email codes, passwords with MFA and breach checks, and social sign-in through OIDC.

  • Organizations and SSO

    Your customers’ organizations with roles and verified domains, and inbound SAML for their identity providers.

  • Hosted and white-labelled

    A hosted account portal on your own domain, React components, and an OAuth server with PKCE and the device flow.

  • Progressive lockout, session limits, and revocation signals are built in.
  • Billed per monthly active user.

Quickstart

Your first call

Install the SDK, set SYLPHX_API_KEY to a key from the console, and call the API. The CLI speaks the same API.

index.ts
import { Sylphx } from '@sylphx/sdk'

// Reads SYLPHX_API_KEY: one key for every Sylphx service.
const sylphx = new Sylphx()
const me = await sylphx.access.whoami({})

for await (const item of sylphx.auth.endUsers.listAll({ parent: me.env! })) {
  console.log(item.name)
}
Install
npm install @sylphx/sdk
CLI
sylphx auth end-users list
