How to Authenticate OpenClaw Model Providers

Authenticating model providers in OpenClaw is mostly about choosing the most boring option that fits your environment. The docs say API keys are usually the most predictable choice for long-lived gateway hosts, while OAuth and subscription-style flows are supported when they match the provider. That is the right framing. Your goal is not to use the fanciest login path. Your goal is to give the gateway a credential source it can actually see and refresh safely.

Step 1: start with an API key unless you have a strong reason not to

The recommended setup flow is simple. Create an API key in the provider console, put it on the gateway host, and check visibility with openclaw models status. For a daemon managed by systemd or launchd, the docs suggest placing the key in ~/.openclaw/.env so the gateway process can read it reliably. Then restart the gateway and run openclaw models status plus openclaw doctor to verify the runtime sees what you think it sees.

export _API_KEY="..."
openclaw models status

cat >> ~/.openclaw/.env <<'EOF'
_API_KEY=...
EOF

openclaw models status
openclaw doctor

Step 2: use onboarding or paste-token when that fits the provider

If you do not want to manage env vars manually, the docs say openclaw onboard can store API keys for daemon use. For manual token entry, the docs also show openclaw models auth paste-token --provider openrouter. Anthropic gets special handling in the documentation because OpenClaw supports Anthropic API keys, Claude CLI reuse, and the older setup-token path. Even there, the docs still call API keys the most predictable option for a long-lived host.

Step 3: verify the credential, not just the file

This is the part operators skip. openclaw models status gives you the normal view. openclaw models status --check exits non-zero when auth is missing or expiring. openclaw models status --probe does live auth probes and shows how OpenClaw evaluates candidates from auth profiles, env credentials, or models.json. The docs even explain what happens when explicit auth ordering excludes a stored profile or when a provider has auth but no probeable model candidate.

Step 4: control which credential OpenClaw actually uses

OpenClaw supports multiple auth profiles per provider, and you can pin them in two ways. Per session, use /model alias-or-id@profileId. Per agent, use openclaw models auth order get, set, or clear. That matters if you have work and personal credentials or if you are testing failover behavior. The docs are good here because they do not pretend multiple credentials automatically lead to clarity. They give you explicit order controls so you can make the choice visible.

openclaw models auth order get --provider anthropic
openclaw models auth order set --provider anthropic anthropic:default
openclaw models auth order clear --provider anthropic

Step 5: know what retries and rotation will do

The authentication docs also explain API key rotation behavior for rate-limit cases. OpenClaw can try alternate keys using a documented priority order such as OPENCLAW_LIVE_PROVIDER_KEY, PROVIDER_API_KEYS, PROVIDER_API_KEY, and PROVIDER_API_KEY_* entries, with Google providers also checking GOOGLE_API_KEY. That retry with another key only happens for rate-limit style errors, not arbitrary failures. So if a key is wrong, broken, or unauthorized, OpenClaw does not mask it by cycling forever.

The best setup is the one you can explain in one sentence: which provider, which credential source, which host owns it, and which status command proves it works. The docs keep pushing that operational clarity, and they are right to do it. In OpenClaw, authentication is not just a login step. It is part of the run-time contract between your gateway and the models you expect it to call.
