AI BriefingVercel Blob adds support for OIDC authentication
Key point
Vercel Blob now supports OIDC authentication, enabling secure data management without long-lived tokens.
Details
Vercel Blob has started supporting OIDC (OpenID Connect) authentication. When connecting a new project, OIDC is applied as the default setting.
OIDC tokens issued by Vercel are short-lived and rotate automatically. This significantly improves security, as there's no longer a need to maintain the previously used long-lived BLOB_READ_WRITE_TOKEN.
Here's how to upgrade an existing store:
- Update the project's
@vercel/blobpackage to the latest version. - Go to the Projects tab of the Blob store.
- Select Upgrade to OIDC from the project context menu.
Functions running on Vercel automatically receive tokens to authenticate requests. Additionally, updating the Vercel CLI allows reading from and writing to private stores from a terminal or agent without long-lived tokens.
