+# Authentication
+
+## Overview
+
+OpenClaw supports two authentication methods for model providers: OAuth and API keys. For Anthropic users, an API key is recommended, though Claude subscription users can alternatively use tokens from `claude setup-token`.
+
+## Key Setup Methods
+
+### API Key Approach (Recommended)
+
+Set your Anthropic API key on the gateway host via environment variable or the `~/.openclaw/.env` configuration file, then verify with `openclaw models status`.
+
+### Claude Subscription Token
+
+Users with Claude subscriptions can run `claude setup-token` on the gateway host and import it using `openclaw models auth setup-token --provider anthropic`.
+
+## Credential Management
+
+Users can control which authentication credential is active through:
+
+- Per-session selection via `/model <alias>@<profileId>` commands
+- Per-agent configuration using auth profile ordering commands
+- Status checks with `openclaw models status` or `openclaw doctor`
+
+## Troubleshooting
+
+Common issues include missing credentials (resolved by rerunning `claude setup-token`) and token expiration (identifiable through status commands). The system provides automation-friendly checks that return specific exit codes for expired or missing credentials.
+
+## Requirements
+
+Users need either a Claude Max or Pro subscription and the Claude Code CLI installed to access setup-token functionality.
