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