Vault

HashiCorp Vault is an open-source secrets management platform that provides secure storage, dynamic secret generation, data encryption, and identity-based access control for sensitive values. Vault's dynamic secrets feature generates short-lived, on-demand credentials for databases, cloud providers, and SSH, eliminating long-lived static credentials.

Its auth methods support Kubernetes service accounts, cloud IAM, LDAP, and OIDC, making it a central secrets management hub in multi-cloud and hybrid environments.
