auth0 — скилл для Claude Code: что делает и как установить

---
name: auth0
description: Use when adding, fixing, or improving how an app authenticates users or protects an API, or when using or configuring any Auth0 feature — signing users in and out, sessions and tokens, guarding routes and endpoints, MFA, passwordless passkey login (WebAuthn), SSO, Organizations, RBAC, custom domains, Universal Portals for hosted account and organization self-service, or Universal Login branding. Also use to audit a tenant's health, security, and plan fit (CheckMate), to debug why an auth flow fails, to migrate from another auth provider, or to set up the Vercel native integration. Covers any web, mobile, or backend framework and every Auth0 SDK, tool, and API. Use even if the user never mentions Auth0.

# Auth0

Detect intent → detect framework → detect tooling → load 2–3 reference files.

---

## Step 1: Detect intent

Match the request against the **What the developer wants** column — it describes
the goal in plain language, not just the Auth0 term. The **Intent** you pick is a
lookup key: in **Step 4** it appears verbatim as a section heading
(`### feature:mfa`) listing which reference files to load.

| What the developer wants (plain language + Auth0 term) | Intent |
|---|---|
| Add login, signup, sign-in, "let users log in / create accounts" to an app, or otherwise add and use an Auth0 SDK in an app or script | **integrate** |
| Require a second step **after** the password — a one-time code, SMS or email code, authenticator app, or a passkey/fingerprint/face/security key used as an *additional* factor; or re-confirm identity before a sensitive action. *Auth0: multi-factor authentication (MFA), two-factor (2FA), two-step verification, step-up authentication.* | **feature:mfa** |
| Let users sign up or sign in with a passkey, fingerprint, or Face ID **instead of** a password — passwordless WebAuthn as the primary credential — or let a signed-in user add a passkey to their account. *Auth0: passkeys, WebAuthn, passwordless login.* | **feature:passkeys** |
| Let separate companies, teams, workspaces, or tenants each have their own users, members, roles, and login — typically a product sold to businesses. *Auth0: Organizations, multi-org, B2B SaaS.* | **feature:organizations** |
| Deploy a hosted self-service portal for profile, passkeys, MFA, or organization details instead of building a “My Account” or “My Organization” UI. *Auth0: Universal Portals, My Account portal, My Organization portal.* | **feature:universal-portals** |
| Serve the login page from your own web address (e.g. `login.example.com`, `auth.company.com`) instead of the default Auth0 URL. *Auth0: custom domain.* | **feature:custom-domains** |
| Build fully custom login/signup screens with your own code or framework, beyond what theme settings allow. *Auth0: Advanced Customization for Universal Login (ACUL).* | **feature:acul** |
| Change how the login page looks — logo, colors, fonts, background, overall theme. *Auth0: branding, Universal Login customization.* | **feature:branding** |
| Bind tokens to the client so a stolen or leaked token can't be reused/replayed from another machine. *Auth0: DPoP (Demonstrating Proof-of-Possession), sender-constrained tokens.* | **feature:dpop** |
| Trade an external or partner token (legacy system, MCP/agent, or another IdP) for Auth0 tokens with no interactive login. *Auth0: Custom Token Exchange (CTE), RFC 8693, subject_token.* | **feature:custom-token-exchange** |
| Audit a tenant for security/config issues, report, then optionally fix findings. *Auth0: tenant audit, CheckMate.* | **audit** |
| Check if a tenant is healthy and on the right plan — two scores + a recommendation. *Auth0: health check.* | **healthcheck** |
| Ask for best practices, "is this secure?", how to handle tokens safely, "how should I do X". *Auth0: guidance / security.* | **guidance** |
| Hit an error: 401 Unauthorized, 403 Forbidden, CORS, callback URL mismatch, redirect loop. *Auth0: debugging.* | **debug** |
| Hit rate limiting: 429 Too Many Requests, quota exceeded. *Auth0: rate limits.* | **debug:rate-limit** |
| Move an existing app off Clerk, NextAuth.js, Firebase, Cognito, Okta, Supabase, Passport.js, or another auth provider. *Auth0: provider migration.* | **migrate** |
| Upgrade the Auth0 SDK itself to a new major version (e.g. Auth0.swift v2→v3, Auth0.Android v3→v4) — breaking changes, deprecated APIs, "update to the latest SDK". *Auth0: SDK major-version upgrade.* | **upgrade-sdk** |
| Install Auth0's Vercel Marketplace integration, connect Auth0 to a Vercel project, or sync Auth0 configuration into a Vercel-hosted Next.js app. *Auth0: Vercel native integration.* | **integrate** |
| Use the Auth0 CLI directly — "create an app/API with the `auth0` CLI", script tenant setup, or automate Auth0 config in CI — with no application framework in play. *Auth0: CLI / tooling-only.* | **tooling** |

### If nothing clearly matches

Pick the closest goal. If the goal is genuinely unclear, ask the developer what they're trying to accomplish - don't guess an intent.

---

## Step 2: Detect framework

> **Skip this step for the `tooling` intent** — a CLI-first request has no
> framework. Go to Step 3, load the tooling reference; only ask about a
> framework if the developer later pivots to integrating auth into an app.

Work top-down. **Stop at the first tier that yields a framework.**

### Tier 1 — Auth0 SDK already installed (strongest signal)

### Node.js / JavaScript / TypeScript — check `package.json` → `dependencies`

Rows are most-specific first: an Ionic/Capacitor project also carries the base
SDK, so check the `@capacitor/browser` rows before it.

| Package | Framework |
|---|---|
| `@capacitor/browser` + `@auth0/auth0-angular` | `ionic-angular` |
| `@capacitor/browser` + `@auth0/auth0-react` | `ionic-react` |
| `@capacitor/browser` + `@auth0/auth0-vue` | `ionic-vue` |
| `@auth0/nextjs-auth0` | `nextjs` |
| `@auth0/auth0-nuxt` | `nuxt` |
| `@auth0/auth0-tanstack-start-react` | `tanstack-start` |
| `@auth0/auth0-react` | `react` |
| `@auth0/auth0-vue` | `vue` |
| `@auth0/auth0-angular` | `angular` |
| `@auth0/auth0-spa-js` | `spa-js` |
| `express-openid-connect` | `express` |
| `@auth0/auth0-fastify` | `fastify` |
| `@auth0/auth0-fastify-api` | `fastify-api` |
| `express-oauth2-jwt-bearer` | `express-jwt` |
| `react-native-auth0` + `app.json` or `app.config.js` present | `expo` |
| `react-native-auth0` (no Expo files) | `react-native` |
| `@auth0/auth0-api-js` | `auth0-api-js` |
| `@auth0/auth0-server-js` | `auth0-server-js` |
| `@auth0/auth0-auth-js` | `auth0-auth-js` |
| `auth0` (the bare package, not `@auth0/*`) | `node-auth0` |

### Python — check `requirements.txt` or `pyproject.toml`

Rows are most-specific first: `auth0-server-python` is the framework-agnostic
server core, so check for a co-installed web framework before falling back to the
bare-SDK row.

| Package | Framework |
|---|---|
| `auth0-server-python` + `flask` | `flask` |
| `auth0-server-python` (no Flask web framework) | `server-python` |
| `auth0-fastapi-api` | `fastapi-api` |
| `auth0-api-python` | `api-python` |

### Java / Kotlin — check `build.gradle` or `pom.xml`

| Dependency | Framework |
|---|---|
| `mvc-auth-commons` (`com.auth0:mvc-auth-commons`) | `java-mvc` |
| `spring-security-oauth2-resource-server` | `springboot-api` |

### .NET — check `*.csproj` or `NuGet.Config`

| Package | Framework |
|---|---|
| `Auth0.AspNetCore.Authentication` (no `.Api` suffix) | `aspnetcore-auth` |
| `Auth0.AspNetCore.Authentication.Api` | `aspnetcore-api` |
| `Auth0.OidcClient.MAUI` | `maui` |
| `Auth0.OidcClient.AndroidX` | `net-android` |
| `Auth0.OidcClient.iOS` | `net-ios` |
| `Auth0.OidcClient.WinForms` | `winforms` |
| `Auth0.OidcClient.WPF` | `wpf` |

### PHP — check `composer.json`

`auth0/auth0-php` powers both PHP web apps and APIs via `SdkConfiguration`'s
`strategy`. The `STRATEGY_API` row is more specific — check it first.

| Package | Framework |
|---|---|
| `auth0/auth0-php` + `SdkConfiguration::STRATEGY_API` (or `strategy: 'api'`) | `php-api` |
| `auth0/auth0-php` (no `STRATEGY_API` / `STRATEGY_REGULAR` or `strategy: 'webapp'`) | `php` |
| `auth0/login` (laravel, no `AuthorizationGuard`) | `laravel` |
| `auth0/login` + `AuthorizationGuard` | `laravel-api` |

> If `auth0/auth0-php` is installed but no `SdkConfiguration` strategy is set
> yet (fresh project), fall through to variant disambiguation below.

### Go — check `go.mod`

| Module | Framework |
|---|---|
| `github.com/auth0/go-jwt-middleware` | `go` |

### Mobile (native)

| Signal | Framework |
|---|---|
| `build.gradle(.kts)` + `com.auth0.kmp:auth0` (Kotlin Multiplatform module) | `kmp` |
| `Package.swift` or `.xcodeproj` + Auth0.swift | `swift` |
| `build.gradle` + `com.auth0.android:auth0` | `android` |
| `pubspec.yaml` + `auth0_flutter` + developer names/targets Windows desktop | `flutter-windows` |
| `pubspec.yaml` + `auth0_flutter` + `flutter.web: false` | `flutter-native` |
| `pubspec.yaml` + `auth0_flutter` + web enabled | `flutter-web` |

### Tier 2 — Framework from non-Auth0 workspace dependencies

If no Auth0 SDK matched, detect the framework from ordinary (non-Auth0)
dependencies. **Stop at the first match.** This picks the base; any web-vs-API
variant is resolved in "Variant disambiguation" below. As in Tier 1, check the
`@ionic/*` rows before their base framework.

| Signal | Base framework |
|---|---|
| `next` in `package.json` | `nextjs` |
| `nuxt` in `package.json` | `nuxt` |
| `@tanstack/react-start` in `package.json` | `tanstack-start` |
| `@ionic/*` + `@angular/core` | `ionic-angular` |
| `@ionic/*` + `react` | `ionic-react` |
| `@ionic/*` + `vue` | `ionic-vue` |
| `@angular/core` in `package.json` | `angular` |
| `vue` in `package.json` (no `nuxt`) | `vue` |
| `expo` in `package.json` | `expo` |
| `react-native` (no `expo`) | `react-native` |
| `react` (no meta-framework above) | `react` (SPA) — see note |
| `express` in `package.json` | `express` (variant below) |
| `fastify` in `package.json` | `fastify` (variant below) |
| `flask` in `requirements.txt`/`pyproject.toml` | `flask` |
| `fastapi` in `requirements.txt`/`pyproject.toml` | `fastapi-api` (variant below) |
| `spring-boot` in `pom.xml`/`build.gradle` | `springboot-api` |
| `laravel/framework` in `composer.json` | `laravel` (variant below) |
| `composer.json` present (no Laravel) | `php` (variant below) |
| `go.mod` present + HTTP server/router | `go` |
| `org.jetbrains.kotlin.multiplatform` plugin + `commonMain` source set (shared Android+iOS module) | `kmp` |
| `Package.swift` or `.xcodeproj` | `swift` |
| `pubspec.yaml` (Flutter) + developer names/targets Windows desktop | `flutter-windows` |
| `pubspec.yaml` (Flutter, web disabled) | `flutter-native` |
| `pubspec.yaml` (Flutter, web enabled) | `flutter-web` |
| `*.csproj` referencing MAUI | `maui` |
| `*.csproj` (WinForms) | `winforms` |
| `*.csproj` (WPF) | `wpf` |
| `*.csproj` ASP.NET (web app or API) | `aspnetcore` (variant below) |

> **`react` note:** a plain React project maps to `react` for an SPA using the
> React SDK, or `spa-js` if the app is framework-agnostic vanilla JS. If unclear,
> ask before loading.

### Tier 3 — Framework from the prompt

If no workspace signal matched, map the framework or language named in the
request. **Stop at the first match.**

| Developer mentions... | Framework |
|---|---|
| Next.js / `next` | `nextjs` |
| Nuxt | `nuxt` |
| TanStack Start (React) | `tanstack-start` |
| Angular (not Ionic) | `angular` |
| Vue (not Nuxt/Ionic) | `vue` |
| React SPA (not Next.js) | `react` |
| vanilla JS / plain JS / no framework SPA | `spa-js` |
| node-auth0 / the `auth0` npm package | `node-auth0` |
| `@auth0/auth0-api-js` / auth0-api-js / low-level resource-server SDK | `auth0-api-js` |
| `@auth0/auth0-server-js` / auth0-server-js / server-side Auth0 session SDK | `auth0-server-js` |
| `@auth0/auth0-auth-js` / auth0-auth-js / AuthClient / low-level OAuth OIDC | `auth0-auth-js` |
| Express (web app / server-rendered) | `express` |
| Express API / protect API routes | `express-jwt` |
| Fastify (web) / Fastify API | `fastify` / `fastify-api` |
| Flask | `flask` |
| FastAPI (web app) / FastAPI API | `server-python` / `fastapi-api` |
| `auth0-server-python` / framework-agnostic Python server SDK / Python OIDC web server with no dedicated reference (Django, Starlette, Sanic, Quart, aiohttp) | `server-python` |
| `auth0-api-python` / Python API JWT validator (resource server / `verify_access_token`) | `api-python` |
| Spring Boot | `springboot-api` |
| Java MVC / servlet | `java-mvc` |
| ASP.NET Core web app / API | `aspnetcore-auth` / `aspnetcore-api` |
| MAUI / WinForms / WPF | `maui` / `winforms` / `wpf` |
| PHP web app / PHP API | `php` / `php-api` |
| Laravel web app / Laravel API | `laravel` / `laravel-api` |
| Go / Golang API | `go` |
| Kotlin Multiplatform / KMP / shared Android+iOS auth code / `com.auth0.kmp` | `kmp` |
| Swift / iOS | `swift` |
| Android / Kotlin | `android` |
| Flutter (native / web / Windows) | `flutter-native` / `flutter-web` / `flutter-windows` |
| React Native / Expo | `react-native` / `expo` |
| Ionic (Angular/React/Vue) | `ionic-angular` / `ionic-react` / `ionic-vue` |

### Variant disambiguation (web app vs API)

Some frameworks have separate web-app and API references. When Tier 1 did not
pin the variant, choose **intent-first**:

| Base | Web-app variant | API variant | Choose API when… |
|---|---|---|---|
| express | `express` | `express-jwt` | protecting API routes / validating JWTs, no server-rendered UI |
| fastify | `fastify` | `fastify-api` | resource server / JWT validation only |
| fastapi | `server-python` | `fastapi-api` | resource server / JWT validation only; a web app with login/logout UI uses `server-python` |
| php | `php` | `php-api` | building/protecting a PHP API, no web UI |
| laravel | `laravel` | `laravel-api` | API-only (token guard), no Blade UI |
| aspnetcore | `aspnetcore-auth` | `aspnetcore-api` | Web API / JWT bearer, no cookie login UI |

If intent is still ambiguous (both a UI and protected endpoints, or unclear),
**state what you detected and ask the developer** web app vs API before loading.

### If nothing matched

Ask the developer what framework/language they are using. Do not guess.

### Conflicts

If Tier 2 (workspace) and Tier 3 (prompt) disagree materially (e.g. the prompt
says "Next.js" but `package.json` has no `next`), **state the conflict and ask**
rather than silently picking. Workspace signals outrank the prompt when both are
present and consistent.

---

## Step 3: Detect tooling

Read the project file tree and the request — a project-context decision.

| Project has... | Load |
|---|---|
| `terraform/` directory OR any `*.tf` files | `tooling-terraform/index.md` |
| Auth0 MCP server active in this agent session | `tooling-mcp/index.md` |
| A request for the Auth0 Vercel Marketplace/native integration, or to connect Auth0 to a Vercel project | `tooling-vercel/index.md` |
| Anything else (default) | `tooling-cli/index.md` |

---

## Step 4: Load reference files

Find the section below whose heading matches the **Intent** you picked in
Step 1, then read the reference files it lists.

### integrate
```
Read: references/framework-{framework}/index.md
Read: references/tooling-{tooling}/index.md
Follow the integration workflow in references/framework-{framework}/index.md.
Use references/tooling-{tooling}/index.md for all Auth0 tenant configuration steps.
```

### feature:mfa
```
Read: references/feature-mfa/index.md
Read: references/tooling-{tooling}/index.md
```

### feature:passkeys
```
Read: references/feature-passkeys/index.md
Then Read the detected SDK's passkey leaf from the hub's "Example code snippets" table (e.g. nextjs → nextjs-auth0.md; react-native/expo → ONLY react-native-auth0.md, which covers react-native-web — never auth0-react.md) — it has the exact API and ceremony; don't implement from framework-{framework}/index.md alone.
Read: references/tooling-{tooling}/index.md
If framework detected: Read references/framework-{framework}/index.md
```

### feature:organizations
```
Read: references/feature-organizations/index.md
Read: references/tooling-{tooling}/index.md
If framework detected: Read references/framework-{framework}/index.md
If multi-tenant architecture / B2B SaaS design question: also Read references/pattern-multi-tenant/index.md
```

### feature:universal-portals
```
Read: references/feature-universal-portals/index.md
Read: references/tooling-{tooling}/index.md
```

### feature:custom-domains
```
Read: references/feature-custom-domains/index.md
Read: references/tooling-{tooling}/index.md
```

### feature:acul
```
Read: references/feature-acul/index.md
Read: references/tooling-{tooling}/index.md
```

### feature:branding
```
Read: references/feature-branding/index.md
Read: references/tooling-{tooling}/index.md
```

### feature:dpop
```
Read: references/feature-dpop/index.md
Read: references/tooling-{tooling}/index.md
If a SPA framework is detected (vue/react/angular/spa-js): Read references/framework-{framework}/index.md
DPoP is SPA-only (no SSR: Next.js/Nuxt) — feature-dpop/index.md states the exclusion.
```

### feature:custom-token-exchange
```
Read: references/feature-custom-token-exchange/index.md
Read: references/tooling-{tooling}/index.md
If framework detected: Read references/framework-{framework}/index.md
```

### guidance
```
Read: references/pattern-security/index.md
If framework detected: Read references/framework-{framework}/index.md (for SDK-specific guidance — token storage, session handling, route protection)
If token handling / JWT vs opaque / storage: Read references/pattern-token-handling/index.md
If multi-tenant / B2B architecture: Read references/pattern-multi-tenant/index.md + references/feature-organizations/index.md
```

### debug
```
Read: references/pattern-common-errors/index.md
If framework detected: Read references/framework-{framework}/index.md
```

### debug:rate-limit
```
Read: references/pattern-rate-limiting/index.md
```

### migrate
```
Read: references/feature-migration/index.md
Read: references/tooling-{tooling}/index.md
If framework detected: Read references/framework-{framework}/index.md
```

### audit
```
Read: references/feature-audit/index.md
Read: references/feature-audit-pricing/index.md
Read: references/feature-audit-remediation/index.md
Read: references/tooling-{tooling}/index.md
Apply findings only with per-command confirmation; verify each change by re-fetch.
```

### healthcheck
```
Read: references/feature-healthcheck/index.md
Read: references/feature-audit/index.md
Read: references/feature-audit-pricing/index.md
Read: references/feature-audit-remediation/index.md
Read: references/tooling-{tooling}/index.md
If a scan can run, do the audit workflow first, then score and recommend a plan. If not, score capability fit and recommend anyway. Never quote Enterprise pricing.
```

### upgrade-sdk
```
Read: references/framework-{framework}/index.md
Follow its "Major Version Migration" section (e.g. Auth0.swift v3, Auth0.Android v4).
This is an Auth0 SDK version bump — NOT a provider migration. Do not load feature-migration/index.md.
If no framework is detected: ask which Auth0 SDK the developer is upgrading.
```

### tooling
```
Read: references/tooling-{tooling}/index.md
No framework file — this is a CLI/tooling-only task (create apps/APIs, script
tenant setup, automate config in CI). If the developer then wants to integrate
auth into an app, return to Step 1 with the integrate intent.
```
