At a glance

Percentage of Square Online checkouts that hit a 3DS 2 challenge and the customer abandoned (did not complete the bank popup). NOT the same as decline (issuer rejected). Different fix: abandons need UX work; declines need issuer-side analysis. Square Online uses 3DS 2 for SCA-required EU traffic and for high-risk US traffic.

Calculation

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

Worked example

7 days of Square Online for a US-EU dual-market DTC brand:
Reads:
  1. EU 13.9% is at the alert threshold. PSD2 SCA forces 3DS challenges; abandon rates of 8, 15% are typical.
  2. US 15% on a small base (3 / 20) is noisy. Don’t over-react below 50 challenges per week.
  3. Frictionless rate matters more. 392 of 412 US sessions skipped 3DS entirely (95.1% frictionless); 122 of 158 EU did (77.2%).
  4. Square Risk Manager interaction. Square Risk can pre-emptively decline high-risk traffic before 3DS even fires; that suppresses both the challenge count and the abandon rate.

Sibling cards merchants should reference together

​
Reconciling against the vendor’s own dashboard

Where to look in the Square Dashboard: Square does not surface 3DS abandon as a headline KPI. Use Reports → Transactions filtered to Status: Cancelled and inspect failure messages. The Risk Manager dashboard shows challenge-issuance counts. Why ours may differ: Cross-connector reconciliation: Stripe and Square 3DS abandon rates for the same business should be comparable in absolute terms (the 3DS protocol is shared); divergence usually reflects different challenge-trigger thresholds in the two PSPs’ risk engines.

Known limitations / merchant FAQs

“My EU abandon rate is 20%, what’s wrong?” Three common causes: (1) the bank popup is in English when the customer browses in French / German / Italian, (2) the return URL after challenge looks broken (popup-blocker scenarios), (3) the merchant’s 3DS branding doesn’t match (customer thinks it’s phishing). Check the locale setting first. “US abandon rate of 5%, is that normal?” US 3DS is mostly issuer-driven (no SCA mandate). 5% is normal; <3% suggests challenges are very low-volume so the metric is noisy. “Can I reduce challenges by tweaking SCA exemptions?” On EU traffic: low-value (<EUR 30), MIT, trusted-merchant, recurring all qualify for exemption. Square Online’s checkout flags these automatically when configured. “Tap to Pay on iPhone, does it 3DS?” No; Tap to Pay is card-present, no 3DS. “My Cash App Pay traffic, do I get 3DS abandons there?” No; Cash App Pay handles auth on the buyer side via the Cash App app, not 3DS. “Multi-currency, does the rate work?” Yes; rate is currency-neutral. “Why is my US challenge rate so much lower than EU?” SCA is mandatory in EU >EUR 30; in US the issuer decides. “What about Square Subscription rebills, do they 3DS?” Mostly no. Recurring transactions qualify for the MIT (merchant-initiated transaction) exemption from SCA. The first transaction (when mandate is set up) goes through 3DS; subsequent rebills are exempt.
