# Hashicorp Vault Integration (JWT)

13-
This module lets you authenticate with [Hashicorp Vault](https://www.vaultproject.io/) in your Coder workspaces by reusing the [OIDC](https://coder.com/docs/admin/users/oidc-auth) access token from Coder's OIDC authentication method. This requires configuring the Vault [JWT/OIDC](https://developer.hashicorp.com/vault/docs/auth/jwt#configuration) auth method.
