OpenClaw Model Provider Authentication Explained

The model-provider authentication story in OpenClaw is really a story about predictability. The docs support a mix of API keys, OAuth, stored auth profiles, Claude CLI reuse, and token-based flows, but the goal is not to collect options for sport. The goal is to make sure the gateway can resolve a usable credential on the machine where it runs, keep multiple profiles straight, and avoid weird token churn when outside tools are involved.

API keys are the baseline for server-style hosts

The docs keep coming back to one recommendation: for an always-on gateway, API keys are usually the most predictable option. That applies broadly and is stated very directly for Anthropic too, even though OpenClaw also supports Anthropic Claude CLI reuse and setup-token compatibility. In other words, OpenClaw gives you flexibility, but its documentation still prefers the path that behaves cleanly under daemon restarts, long uptimes, and explicit billing control.

OAuth exists, but OpenClaw tries to contain the mess

OAuth providers can issue new refresh tokens during login or refresh flows, and some ecosystems invalidate older refresh tokens when that happens. The docs call auth-profiles.json a token sink for exactly this reason. The runtime reads credentials from one place, multiple profiles can coexist, and when OpenClaw reuses credentials from an external CLI it can mirror them with provenance and re-read the external store instead of spending the refresh token itself. That is a very operator-minded design choice.

Auth profiles, ordering, and explicit selection

OpenClaw does not hide multi-credential complexity. It exposes it. You can keep multiple profile ids for the same provider, choose global ordering with auth.order, or pin a specific profile per session with /model alias@profileId. The docs also explain how models status --probe reports excluded_by_auth_order instead of silently trying a stored profile that the explicit order omitted. That kind of visibility matters when you are debugging why the runtime picked the credential you did not expect.

Eligibility rules are not hand-wavy

The Auth Credential Semantics page makes the runtime contract more precise. Stable probe reason codes include ok, excluded_by_auth_order, missing_credential, invalid_expires, expired, unresolved_ref, and no_model. Token credentials can be inline or ref-backed, but invalid or expired timestamps still make them ineligible. SecretRef input is also explicitly blocked for oauth-mode profile credential material. That is all very intentional. OpenClaw wants selection-time and runtime behavior to match.

Rotation and failover stay scoped

The authentication docs also cover alternate API-key rotation for rate limits. OpenClaw can move through a documented priority list of keys when the provider returns rate-limit style failures, but it does not use alternative keys for unrelated errors. That keeps failover useful without turning it into accidental error masking. Again, the theme is predictability. Retry the right failure, rotate within known limits, and keep the final error honest when the problem is not a simple quota event.

The big takeaway is that OpenClaw authentication is not a loose collection of login helpers. It is a structured runtime system with clear storage, ordering, validation, and probe semantics. If you read the docs that way, the auth surface stops feeling complicated and starts feeling disciplined, which is exactly what you want from the layer deciding whether your gateway can talk to expensive models at all.

There is also a practical debugging angle. Because OpenClaw exposes status, probe reasons, and explicit auth-order behavior, you can usually answer the question “why did it pick this credential?” without guessing. That is a bigger deal than it sounds. Authentication systems feel complicated mostly when they are opaque. The docs are trying hard to make this one inspectable.
