# 3DS Abandonment Rate, Klarna

> 3DS Abandonment Rate for Klarna stores. Tracked live in Vortex IQ Nerve Centre. How to read it, why it matters, and how to act on it.

**Metrics type:** [Supporting Metrics](/nerve-centre/overview#metrics-types-explained)  •  **Category:** [Payment Gateway](/nerve-centre/connectors#connectors-by-type)

## At a glance

> Klarna does not use 3DS card-style authentication. Klarna's own consumer-authentication flow (one-tap Klarna app login or email-OTP) replaces it. This card tracks **Klarna-app-authentication abandonment**: customers who started the Klarna login flow but didn't complete.

|                       |                                                                                                            |
| --------------------- | ---------------------------------------------------------------------------------------------------------- |
| **What it counts**    | `COUNT(initiated Klarna auth) - COUNT(completed)` divided by `COUNT(initiated)`. Klarna-app-flow specific. |
| **Healthy baseline**  | 8-15% abandonment is normal.                                                                               |
| **Mobile vs desktop** | Mobile abandons less (Klarna app installed); desktop higher (email-OTP friction).                          |
| **Time window**       | `7D vsP`.                                                                                                  |
| **Alert trigger**     | `>30%`.                                                                                                    |
| **Sentiment key**     | `gauge_inverse: good<=15, warn>30`                                                                         |
| **Roles**             | owner, operations                                                                                          |

## Calculation

Calculated automatically from your Klarna data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

## Worked example

"Helle Mode" 7-day window.

| Channel                     | Auth-initiated | Auth-completed | Abandon rate |
| --------------------------- | -------------- | -------------- | ------------ |
| Mobile (Klarna app one-tap) | 1,420          | 1,322          | 6.9%         |
| Desktop (email OTP)         | 489            | 387            | 20.9%        |
| **Blended**                 | **1,909**      | **1,709**      | **10.5%**    |

What the merchant should notice: mobile abandonment is excellent (6.9%) thanks to one-tap Klarna app sign-in. Desktop friction is higher; if email-OTP delivery slows, abandon rises.

## Sibling cards merchants should reference together

| Card                                                                  | Why pair it                                                      |
| --------------------------------------------------------------------- | ---------------------------------------------------------------- |
| [`kla_decline_rate`](/nerve-centre/kpi-cards/klarna-api/decline-rate) | Decline (Klarna rejected) vs abandon (customer didn't complete). |
| [`kla_success_rate`](/nerve-centre/kpi-cards/klarna-api/success-rate) | Compound view.                                                   |

## Reconciling against the vendor's own dashboard

**Where to look:**

Klarna Merchant Portal → **Conversion** view; abandon rate sits between session-initiation and order-completion.

**Why our number may differ:**

| Reason              | Direction         | Why                                                                             |
| ------------------- | ----------------- | ------------------------------------------------------------------------------- |
| **Time zone**       | Boundary days off | CEST vs UTC.                                                                    |
| **Session timeout** | Either            | Klarna sessions time out at 30 minutes; long-paused sessions count as abandons. |

## Known limitations / merchant FAQs

**Klarna doesn't use 3DS, why this card?**
The card is named for the archetype (3DS-style authentication abandonment); for Klarna it tracks Klarna-app or email-OTP authentication abandons. Same shape, different mechanism.

**Why is mobile so much better than desktop?**
Klarna app one-tap login on mobile; desktop requires email OTP which has 30-90 second delivery delay and inbox-finding friction.

**Email-OTP delivery problems, can I fix?**
Klarna delivers OTPs from a Klarna-controlled domain. Merchants cannot influence delivery; ask Klarna support if delivery rates are anomalous.

**Cart-recovery for Klarna abandoners?**
Yes; cart-recovery email after 1 hour recovers 10-18%.
