Scenario

You are the product data scientist responsible for improving a consumer fintech platform's user authentication experience and increasing the daily login rate. Users access the product via mobile apps and web. Logins can involve MFA and risk-based step-up challenges.

Task

Define the key metrics you would:

• Establish and prioritize to increase the user login rate.
• Monitor continuously (including leading and lagging indicators).
• Use to structure a dashboard or report.

Explain why each metric belongs, how you would compute it (at a high level), and how you’d segment and visualize it to drive decisions.

Hints

• Consider frequency, retention, funnel drop-offs, segmentation, and leading vs. lagging indicators.
• Call out data quality/guardrails (e.g., auto-login vs. user-initiated, bot filtering, security trade-offs).
