+# Qwen Portal
+
+Qwen Portal provides a free-tier OAuth flow for Qwen Coder and Qwen Vision models
+(2,000 requests/day, subject to Qwen rate limits).
+
+## Enable the plugin
+
+```bash
+clawdbot plugins enable qwen-portal-auth
+```
+
+Restart the Gateway after enabling.
+
+## Authenticate
+
+```bash
+clawdbot models auth login --provider qwen-portal --set-default
+```
+
+This runs the Qwen device-code OAuth flow and writes a provider entry to your
+`models.json` (plus a `qwen` alias for quick switching).
+
+## Model IDs
+
+- `qwen-portal/coder-model`
+- `qwen-portal/vision-model`
+
+Switch models with:
+
+```bash
+clawdbot models set qwen-portal/coder-model
+```
+
+## Reuse Qwen Code CLI login
+
+If you already logged in with the Qwen Code CLI, Clawdbot will sync credentials
+from `~/.qwen/oauth_creds.json` when it loads the auth store. You still need a
+`models.providers.qwen-portal` entry (use the login command above to create one).
+
+## Notes
+
+- Tokens expire periodically; re-run the login command when requests fail.
+- Default base URL: `https://portal.qwen.ai/v1` (override with
+  `models.providers.qwen-portal.baseUrl` if Qwen provides a different endpoint).
+- See [Model providers](/concepts/model-providers) for provider-wide rules.
