Improve auth performance

**Description**
Currently helpers lacks proper monitoring support.

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

**Priority**: Low/Medium

Start by locating the authentication helpers and any existing monitoring or performance-related entry points. Determine how monitoring should be configured and what sensible defaults mean from the surrounding project behavior. Done should include configurable monitoring with documented defaults and evidence that authentication performance remains acceptable.
