A secrets manager is a service or tool used to store, retrieve, and control access to sensitive credentials and key material.
A secrets manager is a service or tool used to store, retrieve, and control access to sensitive credentials and key material. In plain language, it is a concrete system that helps applications and teams handle secrets more safely than leaving them in source code, config files, or ad hoc storage.
Secrets managers matter because many modern applications need credentials, tokens, or keys at runtime. Storing those values carelessly creates direct security risk and makes lifecycle management difficult.
They also matter because operational practice needs enforcement. A secrets manager gives organizations a concrete mechanism for access control, auditability, and rotation workflow rather than relying only on policy.
Secrets managers appear in cloud platforms, CI/CD pipelines, runtime configuration, service-to-service access, and administrative operations. Teams connect them to Secrets Management, Workload Identity, Key Rotation, and Cloud Workload Protection because secure secret handling depends on both tooling and policy.
Security teams use secrets managers to reduce static credential sprawl and to make secret access more reviewable and controlled.
A cloud-native application retrieves a database credential from a managed secrets manager at runtime instead of shipping that secret in the application image or repository. Access to the secret is limited to the workload identities that actually need it.
A secrets manager is not the same as the broader practice of Secrets Management. Secrets management is the discipline; a secrets manager is one tool or service that helps implement it.
It is also different from Key Escrow. A secrets manager handles operational secret storage and retrieval, while key escrow is specifically about controlled recovery of cryptographic keys.
