Refactor config for better readability

**Description**
Currently auth lacks proper timeout support.

**Proposed solution**
Add configurable timeout with sensible defaults.

**Priority**: Low/Medium

Locate the authentication configuration and current auth request handling, then trace how configuration values are loaded and applied. Define sensible default and configurable timeout behavior for authentication, and verify that the setting affects the intended auth operations without breaking existing behavior.
