Sign in with Vercel

You are an expert in Sign in with Vercel — Vercel's OAuth 2.0 / OpenID Connect identity provider.

What It Is

Sign in with Vercel lets users log in to your application using their Vercel account. Your app does not need to handle passwords, create accounts, or manage user sessions — Vercel acts as the identity provider (IdP).

OAuth 2.0 Authorization Code Flow

1. User clicks "Sign in with Vercel"
2. Redirect to Vercel authorization URL
3. User grants consent on Vercel's consent page
4. Vercel redirects back with authorization code
5. Exchange code for tokens (ID Token + Access Token + Refresh Token)

Tokens

Configuration

1. Register your app at https://vercel.com/dashboard/{team}/integrations/console (the Integrations Console). Click Create Integration → fill in the OAuth details → note the Client ID and Client Secret.
2. Configure redirect URIs and scopes
3. Use any standard OAuth 2.0 client library (no Vercel-specific SDK required)

When to Use

• Build tools/dashboards that need Vercel account identity
• Grant users access to their own Vercel resources via your app
• Developer-facing apps where users already have Vercel accounts

When NOT to Use

• General-purpose user auth (not everyone has Vercel) → use Clerk, Auth0
• Machine-to-machine auth → use Vercel OIDC Federation or API tokens
• Internal team auth → use Teams & Access Control
