Role & Project Overview
Lead UX Designer (10-month project)
- Refined problem scoping, designed solutions, mapped user flows, and oversaw UAT.
- Focus: Enhancing Multi-Factor Authentication (MFA) usability for OKX, a top-tier crypto exchange serving 100+ countries.
Challenges & User Pain Points
1. Login Roadblocks
- Users unable to access registered MFA methods (phone/email/Authenticator App) faced login failures.
- No clear recovery path led to account lockouts.
2. Security vs. Convenience Trade-Offs
- Mobile/Email MFA: Convenient but vulnerable to phishing.
- Authenticator App: More secure but complex setup/restoration.
3. Poor Exception Handling
Previous design lacked alternative verification paths, blocking users from critical actions like withdrawals.
Design Goals
User-Centric
✔ Simplify MFA setup, updates, and recovery.
✔ Balance security with seamless user flows.
Business-Centric
✔ Support scalability amid 30%+ user growth.
Design Process
Leveraged Jakob Nielsen’s Usability Heuristics across 4 MFA journeys:
Journey 1: Switching MFA Methods During Login
Previous Issues:
- Hidden alternative options under vague buttons (e.g., "Didn’t receive code?").
- Poor context for "reset mobile number."
Refinements:
👉 Clear CTAs: Grouped buttons with icons for visibility.
👉 Contextual Copy: Collaborated with UX writers to clarify actions.
Journey 2: Authenticator App Setup/Update
Previous Issues:
- Cluttered instructions obscured benefits.
- No recovery key reminders.
Refinements:
👉 Step-by-Step Guides: Split into digestible pages (benefits → setup → confirmation).
👉 Recovery Alerts: Highlighted key storage importance.
Journey 3: MFA Management in Security Center
Previous Issues:
- Inconsistent toggle styles and status indicators.
- Buried MFA options under dense text.
Refinements:
👉 Visual Hierarchy: Prioritized MFA settings with icons.
👉 Reduced Clutter: Moved details to sub-pages for scannability.
