HashiCorp Vault 1.15 introduces Microsoft Workload Identity Federation to improve security by enabling applications and services in Azure, Google Cloud, and GitHub to authenticate and access resources without the need for secrets in some scenarios. This technology removes the burden of secrets management from developers, simplifying their experience while providing a powerful tool to secure their applications and services. With WIF, developers can configure Azure AD applications and services to trust tokens issued by HashiCorp Vault, leveraging them to access resources in those applications. The integration aims to deepen Vault's connection with MS Azure, addressing concerns around secrets storage, password leakage, and service downtime associated with secrets rotation.
