Plaintext still works. SecretRefs are opt-in per credential.
Runtime model
- Secrets resolve into an in-memory runtime snapshot, eagerly during activation, not lazily on request paths.
- Cold Gateway startup isolates a retryable SecretRef failure to a known non-Gateway owner when that owner supports isolation. Mapped owner classes include model providers and skills, media/TTS/cron providers, eligible auth profiles, per-agent memory, sandbox SSH, channel accounts, and manifest-declared plugin routes. The Gateway starts, records the owner as configured-unavailable, and emits a redacted degradation warning. Gateway ingress auth, structurally invalid refs or resolved values, fail-closed owners, and refs whose runtime owner is not mapped still fail startup.
- Reload validates each mapped owner independently, then publishes one atomic snapshot. Healthy owners refresh. An eligible failed owner keeps its last-known-good value and becomes stale only when its ref identities, provider definitions, and complete non-secret owner contract are unchanged; a changed or new failed owner becomes cold. A strict failure rejects the reload and preserves the active snapshot.
- Policy violations (for example an OAuth-mode auth profile combined with SecretRef input) fail activation before the runtime swap.
- Runtime requests read only the active in-memory snapshot. Model-provider SecretRef credentials pass through auth storage and stream options as process-local sentinels until egress. Outbound delivery paths (Discord reply/thread delivery, Telegram action sends) also read that snapshot and do not re-resolve refs per send.
- Read-only channel capability discovery evaluates accounts independently. A configured-but-unavailable account does not hide healthy sibling accounts’ message actions, while direct sends through the unavailable account still fail closed.
Egress-time injection (sentinels)
For model-provider credentials backed by SecretRefs, OpenClaw mints an opaque, process-local sentinel during model-auth resolution. Auth storage, stream options, SDK configuration, logs, error objects, and most runtime introspection therefore see a value such asoc-sent-v2.<authenticated-ciphertext>.end, not the provider credential. The guarded model fetch and managed local-provider health probes replace known sentinels in URL and header values immediately before each request leaves the process.
Unknown sentinel-shaped values fail closed before network activity. OpenClaw refuses to send the request rather than forwarding an unresolved sentinel to a provider. Resolved secret values are also registered for exact-value log redaction as a defense in depth measure.
Provider adapters use the latest injection point their SDK supports:
- SDKs with a custom fetch option receive OpenClaw’s guarded fetch, so the SDK retains the sentinel.
- SDKs without a custom fetch option unwrap the sentinel immediately before client construction. Plugin-owned provider streams and agent harnesses unwrap at the final core-owned handoff because those transports do not share OpenClaw’s guarded fetch.
OPENCLAW_SECRET_SENTINELS=off (also accepts 0 or false, case-insensitive) to disable sentinel minting during incident response or compatibility troubleshooting. The kill switch does not disable exact-value redaction registration.
Agent-access boundary
SecretRefs stop credentials from being persisted in config and generated model files, but they are not a process-isolation boundary. A plaintext credential left on disk in a path the agent can read is still readable via file or shell tools, bypassing API-level redaction. For production deployments where agent-accessible files are in scope, treat migration as complete only when all of these hold:- Supported credentials use SecretRefs instead of plaintext values.
- Legacy plaintext residue is scrubbed from
openclaw.json, the SQLite auth-profile store,.env, and generatedmodels.jsonfiles. Retired auth JSON is doctor-owned migration input and is never rewritten bysecrets apply. openclaw secrets audit --checkis clean after migration.- Any remaining unsupported or rotating credentials are protected by OS isolation, container isolation, or an external credential proxy.
Active-surface filtering
SecretRefs are validated only on effectively active surfaces:- Enabled surfaces: retryable failures for mapped, isolatable owners enter cold or stale degradation. Strict, fail-closed, Gateway-required, or unmapped failures block startup/reload.
- Inactive surfaces: unresolved refs do not block startup/reload; they emit a non-fatal
SECRETS_REF_IGNORED_INACTIVE_SURFACEdiagnostic.
Examples of inactive surfaces
Examples of inactive surfaces
- Disabled channel/account entries.
- Top-level channel credentials that no enabled account inherits.
- Disabled tool/feature surfaces.
- Web search provider-specific keys not selected by
tools.web.search.provider. In auto mode (provider unset), keys are consulted by precedence for auto-detection until one resolves; after selection, non-selected provider keys are inactive. - Sandbox SSH auth material (
agents.defaults.sandbox.ssh.identityData,certificateData,knownHostsData, plus per-agent overrides) is active only when the effective sandbox backend issshand sandbox mode is notoff, for the default agent or an enabled agent. gateway.remote.token/gateway.remote.passwordSecretRefs are active if any of these hold:gateway.mode=remotegateway.remote.urlis configuredgateway.tailscale.modeisserveorfunnel- In local mode without those remote surfaces:
gateway.remote.tokenis active when token auth can win and no env/auth token is configured;gateway.remote.passwordis active only when password auth can win and no env/auth password is configured.
- Active
gateway.auth.token/gateway.auth.passwordSecretRefs stay authoritative overOPENCLAW_GATEWAY_TOKEN/OPENCLAW_GATEWAY_PASSWORD; environment credentials are fallbacks when the corresponding local config input is absent.
Gateway auth surface diagnostics
When a SecretRef is set ongateway.auth.token, gateway.auth.password, gateway.remote.token, or gateway.remote.password, gateway startup/reload logs the surface state under code SECRETS_GATEWAY_AUTH_SURFACE:
active: the SecretRef is part of the effective auth surface and must resolve.inactive: another auth surface wins, or remote auth is disabled/not active.
Onboarding reference preflight
In interactive onboarding, choosing SecretRef storage runs preflight validation before saving:- Env refs: validates the env var name and confirms a non-empty value is visible during setup.
- Provider refs (
file,exec, orstore): validates provider selection, resolvesid, and checks the resolved value type. - Quickstart flow: when
gateway.auth.tokenis already a SecretRef, onboarding resolves it before probe/dashboard bootstrap (forenv,file,exec, andstorerefs) using the same fail-fast gate. - Generated gateway token: setup mints
gateway.auth.tokenitself, so reference mode has nothing to prompt for. WithOPENCLAW_GATEWAY_TOKENexported it writes anenvref to that variable, keeping a later rotation authoritative; otherwise it writes the token to the secret store underOPENCLAW_GATEWAY_TOKENand stores astoreref. An existing store entry is reused rather than rotated, so re-running setup never invalidates already-paired clients.

- Plugin-managed exec providers can use

Shared secret store
The shared secret store is a Gateway-wide, team-scoped place for secrets and environment values that should be available to every Gateway process using the same state database. Manage it from Settings → Secrets in the Control UI or locally withopenclaw secrets store. The CLI commands operate on the local state database and do not accept Gateway URL or token options.
Entries have two explicit access modes. Both retain the existing secret and env storage kinds, and either kind can back a SecretRef:
- Protected secret (
kind: "secret") values are write-only after saving. Gateway list results, the Control UI, and CLI list/get output never include them; there is no reveal RPC. A protected value is inert until a supported config field references it with a SecretRef or an enabled, destination-bound secret egress proxy uses it. - Agent-readable environment (
kind: "env") values remain visible to administrators in the Control UI and can be returned bystore listandstore get. OpenClaw adds them as plaintext to Gateway-hosted commands run through its exec tool, after inherited process values and before explicit per-call env. The agent can print, transmit, or persist these values. Protected host keys are ignored with a visible warning.
node exec. Those paths assemble a different child environment. In eligible Codex app-server turns, use gateway_exec to deliberately re-enter the OpenClaw Gateway execution path; gateway_process provides the existing per-session background follow-up. Native Codex shell remains preferred for ordinary local work. The store snapshot is read once per agent run, so entries added or changed mid-run apply from the next run onward.
By default, secret entries are never injected into subprocess environments. When the default-off secret egress proxy is enabled, Gateway-hosted exec commands receive process-local sentinels instead of plaintext values.
Names use the same uppercase grammar as env SecretRefs, and each UTF-8 value is limited to 64 KiB (65,536 bytes). A secret entry must carry a value; empty secrets are rejected because they would surface only as a confusing downstream auth failure. env entries may be empty. This supports PEM keys and service-account JSON without inheriting the smaller limits of ordinary environment variables.
Reference an entry from openclaw.json with the store source:
store SecretRef in the active source config. Names that are not referenced skip that work. Direct CLI writes remain an offline/local path; after changing a config-referenced value with the CLI, run openclaw secrets reload so the active in-memory snapshot picks it up.
Secret egress proxy
The secret egress proxy lets Gateway-hosted agent subprocesses use shared-storesecret entries without receiving their plaintext. OpenClaw puts the existing authenticated sentinel in the subprocess environment, then a Gateway-owned loopback proxy replaces it in request URLs, headers, and streamed bodies immediately before egress.
Each secret must also name the exact HTTPS hosts where substitution is allowed. Hostnames are stored lowercase in ASCII/punycode form and matched exactly; wildcards, suffix matching, and ports are not supported. A secret with no allowed hosts is never substituted. Bind a host without replacing the stored value:
--allow-host to replace the binding with multiple hosts, or use --clear-allowed-hosts to remove every binding. A refused request names the secret and prints the exact store set ... --allow-host ... command needed for that destination.
Enable it explicitly, then restart the Gateway:
$OPENAI_API_KEY is an oc-sent-v2...end sentinel. The proxy replaces it with the stored value only for api.openai.com. A request to an unbound host is refused with Secret "OPENAI_API_KEY" is not allowed for host "<host>". Run: openclaw secrets store set OPENAI_API_KEY --allow-host <host>.
Equivalent config:
HTTPS_PROXYandHTTP_PROXY, with per-run credentials embedded in the loopback proxy URLNODE_USE_ENV_PROXY=1, which makes supported Node.js globalfetchclients honorHTTP_PROXYandHTTPS_PROXYwithout usingNODE_OPTIONSNODE_EXTRA_CA_CERTS,SSL_CERT_FILE,CURL_CA_BUNDLE, andREQUESTS_CA_BUNDLE, pointing at the ephemeral CA certificate- each team-store
secretentry as anoc-sent-v2...endsentinel;enventries keep their existing behavior and precedence
openclaw and a random per-run password. The token expires when the exact agent run closes, including cancellation and replacement. Base64 is not treated as encryption: the listener binds only to loopback, and a process that can read the proxy token from the agent environment can already read the sentinels in that environment. Missing, wrong, or expired credentials receive 407 Proxy Authentication Required and are never forwarded.
The run snapshot registers each sentinel together with its secret name and allowed hosts. After proxy authentication, the proxy looks up the matched sentinel in that run’s registration and authorizes the normalized destination hostname before decrypting the sentinel. A sentinel that is unregistered, unresolved, unbound, or bound to another host is refused before its plaintext is forwarded.
The CA is generated once per Gateway start under the state directory. Its directory is mode 0700, its private keys are mode 0600, it is removed during Gateway shutdown, and OpenClaw never installs it in a system trust store. Requests fail closed when a sentinel cannot be authenticated or resolved; the proxy never forwards or silently strips an unresolved sentinel. Request bodies are scanned as a stream with a bounded carry window, so substitution also works when a sentinel crosses chunk boundaries or appears in a large upload.
bypassHosts contains exact hostnames that must remain end-to-end TLS for certificate-pinned clients. Those hosts use an authenticated blind CONNECT tunnel. No substitution is possible inside the tunnel; a sentinel sent there is safe by construction because it is authenticated ciphertext rather than a credential, so the vendor sees an invalid credential and rejects it.
Current limits:
- HTTP/2 upstream connections are not supported; the proxy uses HTTP/1.1 upstream.
- WebSocket rewriting is not supported.
- Non-443 HTTPS substitution is not a supported compatibility target.
- Identity-scoped secrets are not supported; only the team store participates.
- Allowed-host policy is exact-hostname authorization only. It does not validate the resolved IP or prevent an allowed origin from reflecting credentials.
- Plain HTTP is refused; it is not upgraded or substituted.
- Secret egress applies only to Gateway-hosted exec. Sandbox and remote
nodeexec receive neither proxy variables nor sentinels, so shared-storesecretentries are unavailable there. Provider-native harness subprocesses also do not use this proxy. - Background subprocesses lose proxy authorization when their owning agent run ends, even if the process itself is still alive.
File-backed API keys
Do not putfile:... strings in the config env block. That block is literal and non-overriding, so file:... is never resolved there.
Use a file SecretRef on a supported credential field instead:
mode: "singleValue", the SecretRef id is "value". For mode: "json", use an absolute JSON pointer such as "/providers/xai/apiKey".
See SecretRef Credential Surface for the fields that accept SecretRefs.

MCP server environment variables
MCP server env vars configured viaplugins.entries.acpx.config.mcpServers accept SecretInput, keeping API keys and tokens out of plaintext config:
${MCP_SERVER_API_KEY} and SecretRef objects resolve during gateway activation, before the MCP server process spawns. As with other SecretRef surfaces, unresolved refs only block activation when the acpx plugin is effectively active.
Sandbox SSH auth material
The coressh sandbox backend also supports SecretRefs for SSH auth material:
- OpenClaw resolves these refs during sandbox activation, not lazily on each SSH call.
- Resolved values are written to a temp directory with restrictive file permissions (
0o600) and used in the generated SSH config. - If the effective sandbox backend is not
ssh(or sandbox mode isoff), these refs stay inactive and do not block startup.
Supported credential surface
Canonical supported and unsupported credentials are listed in SecretRef Credential Surface.Runtime-minted or rotating credentials and OAuth refresh material are intentionally excluded from read-only SecretRef resolution.
Required behavior and precedence
- Field without a ref: unchanged.
- Field with a ref: required on active surfaces during activation.
- If both plaintext and ref are present, the ref takes precedence on supported precedence paths.
- The redaction sentinel
__OPENCLAW_REDACTED__is reserved for internal config redaction/restore and is rejected as literal submitted config data.
SECRETS_REF_OVERRIDES_PLAINTEXT(runtime warning)REF_SHADOWED(audit finding when SQLite auth-profile credentials take precedence overopenclaw.jsonrefs)STORE_PLAINTEXT_RESIDUE(audit finding when a stored name still has an equivalent plaintext config value)
serviceAccount accepts inline JSON or a SecretRef. Doctor moves the retired sibling serviceAccountRef into this canonical field when it is unset.
Activation triggers
Secret activation runs on:- Startup (preflight plus final activation)
- Config reload hot-apply path
- Config reload restart-check path
- Manual reload via
secrets.reload - Gateway config write RPC preflight (
config.set/config.apply/config.patch), validating active-surface SecretRefs within the submitted config payload before persisting edits
- Success swaps the snapshot atomically.
- A strict startup failure aborts Gateway startup.
- During cold startup, a retryable resolution failure for a mapped, isolatable non-Gateway owner may publish the snapshot with that exact owner configured-unavailable. Requests for the owner fail with
SECRET_SURFACE_UNAVAILABLE; model-provider owners do not fall back to environment or auth-profile credentials after an explicit ref fails. - Reload and restart-check isolate eligible mapped owners. Unchanged ref identities with unchanged provider definitions and an unchanged complete non-secret owner contract retain their exact last-known-good values as stale; changed or newly configured unresolved refs publish cold for only that owner. A strict reload failure preserves the previously active snapshot.
config.set,config.apply, andconfig.patchaccept syntactically valid unresolved refs for isolatable owners and return a redacteddegradedSecretOwnersreport. Gateway ingress auth, structurally invalid config or resolved values, policy violations, and unknown owners still reject before disk mutation.- Healthy sibling owners resolve and publish normally even when another owner is cold or stale.
- Providing an explicit per-call channel token to an outbound helper/tool call does not trigger SecretRef activation; activation points remain startup, reload, and explicit
secrets.reload.
Degraded and recovered signals
When reload-time activation fails after a healthy state, OpenClaw enters degraded secrets state, emitting one-shot system events and log codes:SECRETS_RELOADER_DEGRADEDSECRETS_RELOADER_RECOVERED
- Degraded: healthy owners refresh, stale owners keep last-known-good, and cold owners remain unavailable.
- Recovered: emitted once after the next successful activation.
- Repeated failures while already degraded log warnings but do not re-emit the event.
- A strict startup failure never emits a degraded event, because runtime never became active. A successful startup with cold owners logs the owner degradation but does not emit a reloader event.
- Ref-scoped startup and reload failures emit a structured
SECRETS_DEGRADEDwarning for each affected owner. Provider-scoped outages emit oneSECRETS_PROVIDER_DEGRADEDwarning with the provider and complete affected-owner list instead of repeating the provider failure per owner. Warnings include a redacted reason,coldorstaleowner state, and theopenclaw secrets reloadretry hint. They never include resolved values or SecretRef ids. openclaw doctorlists cold and stale owners with their affected config paths, redacted reason, and retry guidance.
Command-path resolution
Command paths can opt into supported SecretRef resolution via a gateway snapshot RPC. Two broad behaviors apply:- Strict command paths
- Read-only command paths
For example
openclaw memory remote-memory paths and openclaw qr --remote when it needs remote shared-secret refs. They read from the active snapshot and fail fast when a required SecretRef is unavailable.- Snapshot refresh after backend secret rotation is handled by
openclaw secrets reload. - Gateway RPC method used by these command paths:
secrets.resolve.

Safety model:- Preflight must succeed before write mode.
- Runtime activation is validated before commit.
- Apply updates files using atomic file replacement and best-effort restore on failure.
Legacy auth compatibility notes
For static credentials, runtime no longer depends on plaintext legacy auth storage.- Runtime credential source is the resolved in-memory snapshot.
- Legacy static
api_keyentries are scrubbed when discovered. - OAuth-related compatibility behavior remains separate.
Control UI
Open Settings → Secrets to list, add, edit, bulk-import, or soft-delete team-scoped entries. Choose Protected secret for write-only values used by SecretRefs or destination-bound Gateway egress. Choose Agent-readable environment only when Gateway-hosted agent commands must receive plaintext and the agent may print, transmit, or persist it. Bulk Add accepts dotenvNAME=VALUE assignments, including quoted multiline values. Protect credential-like names automatically defaults credential-shaped names to protected mode.
This store page manages values only. Configure the corresponding store SecretRef on a supported field through its settings form or the raw editor. Identity-scoped entries are reserved for a later release and are not exposed by this page.
