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

Token	Lifetime	Purpose
ID Token	Signed JWT	Proves user identity (name, email, avatar)
Access Token	1 hour	Bearer token for Vercel REST API calls
Refresh Token	30 days	Silent re-authentication (rotates on use)

Configuration

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.
Configure redirect URIs and scopes
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
