2023 to present

I lead design for passkeys and Klarna's authentication framework, a launch expected to save $69M USD a year. I also led design for account linking and Sign in with Klarna for major partners, and co-led the redesign of MyKlarna, where people manage their account.

What’s a Rich Text element?

Sunheading

Another subheading

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.

And here is a really important quote that I'll want to highlight.

$69M expected yearly impact, plus 6 percentage points sign-in conversion, 150M+ people signing in

Project objectives...

Sign-in is the doorway to everything Klarna offers its 150M+ users. The goal was to make getting in faster and safer at the same time, and to keep people signed in across Klarna and its partners.

Project Details...

Passkeys rollout

I led the UX for Klarna's move to passkeys, from benchmarking on mobile and desktop to flows, prototypes and the overall UX strategy. The aim was a passkey experience that stands up against the best in the world, balanced against stakeholder requirements and technical constraints.

Expected impact: $69M USD a year, from reduced costs and improved conversion rates.

Account linking: staying signed in

I led the UX for keeping people signed in with merchants through a linked Klarna account. It meant working through hard technical and usability problems, weighing security and legal risk against business goals, and making the result work for every type of merchant.

Impact: a 6 percentage point increase in sign-in conversion.

Sign in with Klarna for major partners

For Klarna's largest partners I designed the account linking experience inside their own bespoke integrations: account creation, login, the link itself and how people manage it afterwards. I worked directly with the partners' designers and with Klarna teams across three domains.

MyKlarna

Together with Klarna's central UX team, I co-led the redesign of MyKlarna, working with stakeholders from individual teams up to CXO and CEO level. I owned the personalisation sections and third-party connections, and improved how people manage their name, display name and account details. Incorrect account information was behind a large share of rejected purchases, so making it easy to keep details right matters to people and to the business.
