Sign JWTs from your Functions without managing private keys
PreviewVerifiedAdded Sep 22, 2026
Vercel KMS lets you sign JWTs and arbitrary messages from your Vercel Functions using managed asymmetric signing keys, so private keys never live in your code or environment variables. Your function authenticates with its Vercel OIDC token, and the private key stays inside Vercel's key management service while verifiers use only the public key.
