Azure Key Vault securely stores and controls access to secrets, keys, and certificates for applications and services.
DESCRIPTION
Azure Key Vault is a managed service for protecting cryptographic material and secrets. It integrates with Azure AD for authentication and RBAC authorization, supports HSM-backed keys, and provides auditing and rotation. Applications access secrets via client libraries and managed identities, minimizing credential exposure. Key Vault helps enforce least privilege, centralized secret governance, and compliance. It’s commonly used to secure app settings, database credentials, tokens, and encryption keys.
