Do not treat every incident as a reason to rotate every OpenBao key: revoking a token, replacing a cloud key, rotating unseal material, rotating the storage keyring, and rewrapping Transit ciphertext address different risks.
The right response depends on the exposure and the service’s continuity needs. OpenBao’s documentation describes the individual controls, but it cannot establish what an attacker accessed or prescribe one containment choice for every deployment.
First determine what may have been compromised
Build a working scope before choosing a rotation action. Identify the suspected identity or credential, the OpenBao authentication path and secret engines it could reach, the likely exposure window, and the applications or external systems that depend on affected secrets. Use available OpenBao audit records alongside identity-provider, infrastructure, and application evidence. Preserve relevant evidence where feasible while containing access.
These exposure types call for different actions:
| Suspected exposure | Primary response | What that response does not fix |
|---|---|---|
| One OpenBao client token | Revoke the token, then assess its leases and the secrets it could access. | It does not invalidate a copied cloud, database, or API credential at that credential’s issuer. |
| An auth method or its issuance path | Assess revocation by the auth-method prefix, including tokens and dynamic secrets issued through that path. | It does not by itself rotate unrelated static credentials already copied out of OpenBao. |
| A static secret stored in OpenBao | Replace it at the system that issued it, update dependent workloads, and retire the old value when safe. | Revoking an OpenBao token does not make the external credential unusable. |
| Unseal or recovery material | Assess the relevant key-rotation procedure and quorum requirements for the deployed seal configuration. | It is not the same operation as rotating the backend encryption key or a Transit key. |
| OpenBao host or storage | Treat the incident as potentially broader than a credential leak; investigate access to stored data and key material and plan containment around the deployment. | Changing a client token alone does not repair a compromised server or storage layer. |
| A Transit key or Transit-backed auto-unseal key | Rotate the affected Transit key as appropriate, and rewrap existing ciphertext if it must be upgraded to a newer key version. | Rotation alone does not rewrite existing ciphertext. |
These are scoping distinctions, not claims that a particular exposure occurred. Logs and local architecture determine the actual access window, blast radius, and safest service-continuity plan.

Revoke OpenBao access and associated leases
Revoke a known token
Revoke a known compromised token directly, or use its accessor if you need to act without handling the token value itself. OpenBao accessors support limited token operations, including revocation. OpenBao also documents listing accessors as a way to audit and revoke the active token set. See the OpenBao token documentation and the token-revocation policy documentation for the deployed release.
Revoking a token also revokes leases associated with it. Check that the expected leases were revoked and account for any dependent workloads that must reconnect or obtain replacement credentials.
Revoke tokens issued through a compromised auth path
If the auth method or its issuance path may be compromised, evaluate revoking by that method’s prefix rather than stopping at one known token. OpenBao documents prefix revocation as a way to revoke tokens issued through the path and dynamic secrets generated by those tokens. This can have a wider operational impact than revoking a single token, so identify affected workloads and dependencies before using it when circumstances permit.

OpenBao policy documentation also describes force revocation, which ignores backend errors. Treat it as an emergency choice rather than a routine shortcut: a backend error can mean an external credential was not successfully revoked. Verify the result with the backend or issuer instead of assuming that an OpenBao revocation record proves every downstream credential is unusable.
Rotate external credentials where they were issued
For a cloud IAM key, database credential, external API token, SSH credential, certificate, or other static secret that may have been read, replace it at the issuing system. OpenBao stores or brokers credentials; it does not necessarily control whether a copied credential remains valid at its issuer.
- Create or issue the replacement. Follow the issuer’s supported rotation process, including any required overlap period.
- Update dependent applications. Deliver the replacement through the approved secret-management path and account for caches, connection pools, scheduled jobs, and replicas that may retain the old value.
- Verify the new credential. Confirm that affected workloads can authenticate and perform their required functions with it.
- Disable or revoke the old credential. Do so when the issuer’s overlap and availability constraints allow, then verify that use of the old value fails.
OpenBao’s use-case guidance identifies leaked static credentials as a threat and recommends short-lived, just-in-time credentials where applicable. That can reduce the useful lifetime of future exposures, but it does not replace rotating a credential already suspected of being copied.

Choose the right OpenBao key rotation
“Rotate the OpenBao key” can refer to different key material. Decide which layer is implicated before acting. OpenBao’s key-rotation documentation for 2.7.x distinguishes root or unseal material from the backend encryption key; root-key rotation also changes Shamir unseal shares. Recovery-key rotation is a separate procedure where supported, and these operations involve quorum requirements.
| Material or operation | Effect | Important limitation |
|---|---|---|
| Root or Shamir unseal material | Changes the relevant root/unseal material; root-key rotation also changes Shamir unseal shares. | It is distinct from rotating the backend encryption key. Follow the procedure and quorum requirements for the deployed configuration. |
| Recovery keys | Rotates recovery material through a separate path where supported. | Do not assume every seal configuration supports the same recovery-key procedure. |
| Backend encryption keyring | Adds a new key for subsequent writes. | Previous key versions remain available to decrypt older stored data; rotation does not retroactively erase or re-encrypt it. |
Keyring rotation is relevant when the backend encryption key is implicated or rotation is otherwise required by your security policy. It does not repair a leaked external credential, and it should not be described as retroactive removal of old ciphertext.

Rotate Transit keys and rewrap existing ciphertext separately
Transit key rotation changes the key version used for new encryption. Existing ciphertext remains associated with its earlier version unless it is rewrapped. Rewrap is the separate operation that upgrades existing ciphertext to the latest key version without returning plaintext to the caller. Retain old versions for decryption until migration and recovery requirements are satisfied.

For AES-GCM keys, OpenBao’s Transit documentation says rotation should occur before approximately 232 encryptions have been performed by a key version, following NIST SP 800-38D guidance. This is key-use guidance, not a credential-rotation deadline or an incident-response statistic.
If Transit is used for auto-unseal, OpenBao documentation cautions against deleting or disabling old keys that may still be needed for older data. Confirm what the deployed configuration depends on before retiring any key version.

- The compromised OpenBao token no longer works, or the intended auth-path token set has been revoked.
- Expected leases were revoked and affected services have obtained valid replacement credentials.
- The new external credential works at its issuer, and the old credential fails after it is disabled.
- Applications and scheduled workloads have reauthenticated; failures caused by stale cached values have been addressed.
- Required older ciphertext remains decryptable, and any planned Transit rewrap has been checked against recovery needs.
- OpenBao audit and monitoring remain functional so new authentication and access can be observed.
OpenBao recommends revoking initial root tokens after setup and using more tightly controlled authentication. After containment, review root-token handling, policy scope, and whether short-lived credentials can replace long-lived static secrets.
Check the procedure against your deployed release
OpenBao’s public documentation includes 2.7.x key-rotation material and some development documentation under /next. Endpoint behavior and available procedures can vary by release. Confirm the relevant documentation against the version you run before executing a production change, especially for quorum operations, force revocation, recovery keys, and Transit-backed auto-unseal.
General documentation cannot tell you whether a seal mechanism was compromised, which external credentials were read, or whether to isolate, seal, fail over, or preserve service availability in your incident. Those decisions require local logs, architecture, and incident evidence; no one containment choice is universally correct.
