Optimize models for large datasets

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

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

**Priority**: Low/Medium

The issue does not name any files, tests, or entry points; first clarify whether the work is optimizing models or adding analytics to authentication. Then identify the authentication and analytics entry points, define the configurable options and sensible defaults, and add tests showing that configuration works.
