Login Redesign

The login page had been stalled since 2023. A mockup I put together in 2025 got it moving again, and then it turned into something bigger than a visual refresh.

ROLE UI Designer · IAM UX · Accessibility · Design System Integration
SCOPE Enterprise login surface — SSO, MFA, tenant routing, federal agency users
PROBLEM Login was standalone legacy code — disconnected from the design system, unbranded, and showing a single generic "Login Failed" for 15+ distinct IAM failure modes including locked accounts, expired SSO sessions, MFA timeouts, and tenant mismatches

The project had been sitting since 2023, not because the design was complicated, but because nobody had written down what should happen after a failed MFA attempt. Or a locked account. Or an expired SSO session. I counted 15 distinct failure modes. The original design handled one of them.

The Context

A 2-year stall. Restarted in 3 days.

This project had been stuck since 2023. Undefined requirements, no clear owner. In 2025, a mockup I put together sparked renewed interest. I was handed a "visual refresh." It became more than that.

The login page is the first surface every cloud customer sees permanently. When accounts activate, users are moved from product-specific URLs to this centralised page with no opt-out. A dated, inconsistent experience for a cybersecurity company creates a trust problem before anyone has even signed in.

I counted 15 distinct failure modes. The original design handled one of them.

What I Changed

Logic first. Then visuals.

01
Microcopy that reflects the action

"Confirm" → "Verify", "Send Code", "Reset Password." "Authenticating..." → "Signing you in..." with a visible loading indicator. Every label now reflects consequence, not just direction.

Effect: In security-critical flows, ambiguous labels are a trust problem, not just a UX problem. Users now understand what they’re committing to before they act. "Stuck login" support tickets dropped — users could tell the system was working, not frozen.

02
A design system login — for the first time

Brought the login page into Shield Design System. Same typography, spacing scales, button components, and focus states as the core product. The flow now feels like a continuation of the platform, not a separate site.

Effect: The login surface stopped looking like a different product. For security professionals trained to flag unfamiliar login pages as phishing attempts, visual consistency is a trust signal, not just an aesthetic one.

03
Authentication errors moved to banners

Initially designed inline errors on form fields. Then realised authentication errors come from the backend — not the UI layer. Inline form errors were architecturally wrong for this context. Shifted to banner alerts.

Effect: Error placement now reflects how the system actually works. A small change in the file. The reasoning behind it — that design has to reflect system architecture — changed how I approach all error state work.

Outcome

Shipped. Cleaner handoff. Fewer open questions.

Unified visual language across login, MFA, error states, Forgot Password, and Context Switching — all aligned to the design system for the first time.
Reduced "stuck" support tickets. Explicit status messaging addressed the most common user confusion during authentication latency.
Engineering had what it needed. Mapped logic, edge cases, and error states before handoff eliminated the ambiguity that had kept this project stalled for two years.
15+ IAM failure modes mapped to specific, actionable messages — SSO-related support tickets dropped post-launch.
"Once I mapped all 15 failure modes, the engineers stopped asking clarifying questions. The handoff took less back-and-forth than anything I’d shipped in the previous six months."
