A returning customer loads your checkout, gets asked for a password, guesses wrong twice, and requests a reset email. Most of them never come back to finish the order. According to the Baymard Institute’s ongoing cart abandonment research, the average documented cart abandonment rate sits at 70.19%, and Baymard’s checkout usability studies found that 19% of shoppers have abandoned a purchase specifically because the site forced them to create an account. Passkeys attack that exact failure point, and in 2026 the tools to add them to your store are finally mainstream.
What a passkey actually is
A passkey replaces your password with a cryptographic key pair. The private key stays locked on the customer’s device and gets unlocked with a fingerprint, face scan, or PIN. Nothing shared is stored on your server, so there is nothing for attackers to steal, phish, or stuff into login forms. The standard comes from the FIDO Alliance and is now built into iOS, Android, Windows, Chrome, and Safari, with credentials syncing across devices through iCloud Keychain and Google Password Manager.
For a shopper, the experience is the same one they use to unlock their phone dozens of times a day. No password to remember means no reset email to wait for at the worst possible moment.
The speed numbers are hard to ignore
Google’s own research measured passkey sign-in at 14.9 seconds on average versus 30.4 seconds for passwords, roughly twice as fast. The FIDO Alliance’s 2025 Passkey Index reported a 73% reduction in login time compared with traditional multi-factor authentication. Travel site Kayak, an early adopter, reported sign-in time reductions of about 50% along with fewer support tickets, in a case study published by Google’s developer team.
Support load matters too. Forrester research on enterprise password management has found that up to 50% of IT helpdesk tickets relate to password resets. For a small store, that is hours of customer service time spent on a problem that passkeys remove entirely.
Most stores still have not moved
Passkey vendor Corbado audited 50 leading B2C brands across the US, UK, Europe, and Australia for its 2026 e-commerce authentication benchmark (a vendor report, but the audit results are verifiable on each brand’s login page). Only 19 of the 50 supported passkeys. Amazon leads the pack with over 320 million customers enrolled, and Target, Walmart, Best Buy, and Costco have all shipped support. The rest still lean on passwords plus SMS codes.
That gap is your opening. Shoppers trained by Amazon and their own phones now expect biometric login. A small store that offers it feels modern; one that emails password reset links feels like 2015.
The security case is just as strong. Akamai’s research found bots make up 42% of overall web traffic, and Imperva’s 2025 Bad Bot Report puts bad bot traffic in retail at 33%. Much of that is credential stuffing, the same automated abuse behind the card testing bots that skip your checkout form. Passkeys shut that door because there is no password list to replay. NIST has deprecated SMS as an authentication channel, so if your fallback plan is texting codes, it is worth reading our rundown of the seven security threats targeting small stores in 2026.
2026 is the tipping point
The payments layer is now pushing merchants in the same direction. PYMNTS reported in February 2026 that PayPal has expanded passkey login for consumer accounts in the US and additional markets, and that Stripe has published developer guidance encouraging merchants to implement passkeys through the WebAuthn standard. When the two companies sitting at the center of online checkout both promote the same login model, the follow-on adoption tends to be fast.
Account takeover also feeds chargebacks: a criminal buying with a stolen account looks like a customer until the dispute lands. If disputes are already a problem for you, see our piece on friendly fraud rising for 83% of merchants.
How to add passkeys to your store
Start with your platform. Shopify merchants get passkey-style login through Shop accounts with no extra work. WooCommerce and WordPress stores can add WebAuthn support through established login plugins, or through hosted authentication providers that handle enrollment and recovery for you. If you run a custom stack, Stripe’s WebAuthn guidance is a practical starting point for your developer.
Three rules make the rollout work. First, offer, never force: show a “save a passkey for faster checkout” prompt right after a successful purchase, when trust is highest. Second, keep a fallback: email-based recovery stays available for customers who switch devices. Third, measure it: track login success rate and time-to-login before and after, because those numbers are your business case. Login friction is one of several fixable leaks in checkout; pairing passkeys with the tactics in our guide to cutting cart drop-off with AI support compounds the gains.
The takeaway
Passwords are a conversion tax and a security hole at the same time. The measured data says passkeys cut login time roughly in half, and the audit data says most of your competitors have not implemented them yet. That combination does not stay open for long. Put passkey support on your list for this quarter, not someday.
