SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Adding user login to an application normally requires handling passwords, account creation, and session management. This Skill guides you through delegating all of that to Vercel's OAuth 2.0 / OpenID Connect identity provider, so users authenticate with their existing Vercel accounts. ## Core Features & Use Cases - Authorization Code Flow Guidance: Walks through the full OAuth 2.0 flow from the sign-in redirect to the consent page and code exchange. - Token Management: Explains the ID Token (signed JWT with user identity), Access Token (1-hour bearer token for the Vercel REST API), and Refresh Token (30-day silent re-authentication with rotation). - App Registration: Covers creating an integration in the Vercel Integrations Console, configuring redirect URIs and scopes, and obtaining the Client ID and Client Secret. - Use Case: You are building a developer dashboard and want users to log in with their Vercel accounts and access their own Vercel resources through your app, without building an auth system from scratch. ## Quick Start Help me implement Sign in with Vercel in my Next.js app so users can log in with their Vercel accounts.

Frequently Asked Questions about sign-in-with-vercel

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement Sign in with Vercel in my app?▼

Register your app in the Vercel Integrations Console to get a Client ID and Client Secret, configure redirect URIs and scopes, then use any standard OAuth 2.0 client library to run the authorization code flow. No Vercel-specific SDK is required.

What tokens does Sign in with Vercel return?▼

The flow returns three tokens: a signed JWT ID Token proving user identity, an Access Token valid for 1 hour for Vercel REST API calls, and a Refresh Token valid for 30 days that rotates on each use for silent re-authentication.

When should I use Sign in with Vercel instead of Clerk or Auth0?▼

Use Sign in with Vercel for developer-facing apps where users already have Vercel accounts and need access to their own Vercel resources. For general-purpose consumer auth, use Clerk or Auth0 since not everyone has a Vercel account.

Can I use Sign in with Vercel for machine-to-machine authentication?▼

No, Sign in with Vercel is designed for user authentication via the OAuth consent flow. For machine-to-machine scenarios, use Vercel OIDC Federation or API tokens instead.

Do I need a Vercel SDK to integrate Vercel OAuth login?▼

No Vercel-specific SDK is required. Sign in with Vercel follows the standard OAuth 2.0 and OpenID Connect protocols, so any standard OAuth 2.0 client library in your language or framework works.
