 Running `ccs config auth setup` on the outer host shell updates that machine's own `~/.ccs`, not the Docker volume mounted into `ccs-cliproxy`. For the integrated stack, configure auth inside the container or provide the auth env vars in Compose.

 ```bash
-docker exec ccs-cliproxy node -e "console.log(require('bcrypt').hashSync('your-password', 10))"
+docker exec -i ccs-cliproxy node -e "const fs=require('fs'); const bcrypt=require('bcrypt'); const password=fs.readFileSync(0,'utf8').trimEnd(); console.log(bcrypt.hashSync(password, 10));"
+# then type/paste the password followed by Enter (stdin is not exposed via argv)
 ```
 
 > **Note:** Do not commit the password hash in `docker-compose.yml`. Use Docker secrets or a `.env` file (not tracked in git) for sensitive values like `CCS_DASHBOARD_PASSWORD_HASH`.
