Passwordless Login & Signup Redesign

A mobile-first redesign focused on faster registration and passwordless email verification while aligning web and mobile on one API.

Scope: I was responsible for the full UX/UI design and handoff specifications. I was not involved in production implementation.

Evidence, scope, and outcome.

Problem
Long mobile registration and inconsistent authentication behavior across platforms.
Contribution
Owned the complete UX/UI design, edge cases, flow logic, and handoff specifications.
Delivery
Design and handoff only; no production implementation claim.
Evidence
Full flow map, error states, final UI, and Figma source.
Outcome
The 1-2 minute registration figure is a design target, not a verified production result.

The Problem

The existing experience was not optimized for mobile and the registration page was too long, creating friction and increasing completion time.

  • Dense mobile layout, difficult typing, unclear progress
  • Registration took roughly 3-4 minutes
  • Mobile and desktop used different APIs, producing mismatched behavior

Goals

The redesign followed one main idea: reduce steps, typing, and mistakes.

Faster registration

Reduce completion time from 3-4 minutes to a 1-2 minute design target.

Mobile-first clarity

Improve readability, spacing, and tap targets.

Passwordless login

Users receive an email code with no password required.

Unified behavior

Use one API for consistent web and mobile experiences.

03 / Case study

The Solution

The experience was redesigned end to end with one clear decision per screen.

Shorter registration

Cleaner steps reduce decision fatigue.

Email OTP login

Email to code to verification to continue.

Clear error states

Predictable invalid-code, resend-timer, and captcha feedback.

Same API

Consistent behavior and fewer edge-case bugs across platforms.

New Flows

The full flow map includes happy paths and edge cases for login and registration.

  • Invalid email format
  • Expired or incorrect OTP
  • Resend timer and throttling
  • Captcha not accepted
  • Existing email routes to login

Final UI

Screens minimize typing, clarify progression, and provide predictable feedback.

06 / Case study

Impact

The redesign simplified the proposed authentication experience and aligned both platforms.

  • Registration design target: 1-2 minutes
  • Passwordless OTP authentication
  • One API shared by web and mobile

Notes & Learnings

Simplicity is a feature

Cutting steps and clarifying states improves speed and confidence.

Consistency reduces bugs

One API supports predictable UX and fewer edge-case inconsistencies.

What I'd measure next

  • Signup completion rate
  • Time to complete signup
  • OTP success vs password login
  • Drop-off from email to OTP to completion
