The best WooCommerce biometric plugins let customers log in with a fingerprint or face scan instead of a password. They run on the WebAuthn standard built into modern browsers and phones. Passwords are the weak point of most login flows.
Store owners are catching on fast, and the plugin market for this has grown from a handful of niche tools into a real category with options at every price point. Below are six plugins worth a look, what each one does under the hood, and how to tell which one fits your store.
What Is WooCommerce Biometric Login?
Biometric login swaps the password field for a fingerprint scan, a face scan, or a security key, using WebAuthn, the browser standard backed by Apple, Google, and Microsoft.
The flow is simple:
Customer registers a fingerprint or face scan once → taps a login button next time → verifies with their device → they’re in. No typing, no password reset email, no delay before checkout.
The customer’s biometric data never leaves their device. Your server only ever sees an encrypted key pair. It never sees the fingerprint or face scan itself. That’s what makes this approach both more secure and easier to explain to privacy-conscious customers.
What to Check Before Choosing a Plugin
Run through these checks first, or you’ll likely be reinstalling something different in three months.
- HPOS compatibility: WooCommerce’s High-Performance Order Storage is now the default. Any plugin should declare compatibility on its page. See our guide on making a WooCommerce plugin HPOS compatible for the technical detail.
- Where the login button appears: Some plugins only support the account page; others add it to login and checkout too. Account-only won’t reduce checkout friction.
- Role restrictions: Can you limit biometric login to specific customer groups? Wholesale and membership stores usually need this, and not every plugin offers it.
- Fallback behavior: A well-built plugin drops back to password login gracefully when a device doesn’t support WebAuthn.
- Support and update frequency: Check the changelog. A stale plugin is a risk because WebAuthn shifts often across browsers.
Every plugin here also requires HTTPS. If your store isn’t there yet, that’s step zero, worth pairing with a WooCommerce security checklist.
6 Best WooCommerce Biometric Plugins: Everything you need
Here’s the lineup, ranked by how well each one fits a WooCommerce store specifically rather than a general WordPress site.
1. WooCommerce Biometric Login by DevDiggers
WooCommerce Biometric Login is our own passkey plugin, built by DevDiggers for store logins. Customers sign in with Face ID, Touch ID, Windows Hello or a fingerprint on My Account, checkout and wp-login.php. The store keeps only a public key and never sees a fingerprint or face.
The WooCommerce biometric login plugin was built for WooCommerce login forms and is not a general WordPress tool adapted for stores. A short setup wizard places the button, styles it and turns on recovery codes and alerts. We read its settings and source code in October 2026 for this update.
Best for
WooCommerce stores with repeat customers, subscription members or B2B buyers who want passkey login on My Account and checkout. It also suits stores that must put wp-admin staff behind passkeys.
Pricing
- Live Demo available
- Single-site license: $49/year
- 5 Sites License: $199/year
- 10 Sites License: $299/year
- Every plan includes one year of updates, priority support and a 14-day refund. There is no free edition as of October 2026.
Subscription Includes
- Passkey buttons on every login: My Account, the classic checkout login and wp-login.php each get a Sign in with a passkey button.
- Passkey autofill: Saved passkeys show up in the username field on supported browsers for a one-tap sign in.
- Recovery codes for a lost device: Customers save ten one-time codes that get them back in without an email reset.
- Required passkeys for staff: Pick the roles that must add a passkey and give them a grace period with reminders.
- Passkey-only sign in: For the roles you choose, the password stops working once the user has a passkey.
- Invitations at the right moment: Customers are asked to add a passkey after a password login, after signup or on the order received page.
- Security emails and alerts: Customers hear when a passkey is added or removed, and you get alerts for lockouts and staff sign ins.
- Dashboard and activity log: Cards track passkey logins, success rate and adoption, and the log exports to CSV.
Limitations
- The Checkout block has no login form of its own. Its login link opens the My Account login with the passkey button.
- There are no magic links, OTP or TOTP codes, and no passkey-only signup.
- Brute force protection counts passkey and recovery code attempts per IP. It does not cover password logins.
- It needs HTTPS and the OpenSSL, mbstring and GMP or BCMath PHP extensions.
Worth knowing: Of the six plugins here, it is the only one with recovery codes for a lost device and required passkeys for staff roles. It is also the only one that invites customers to add a passkey on the order received page.
2. Biometric Login for WooCommerce by FME
Biometric Login for WooCommerce by FME is the option most store owners stumble onto first, since it sits right on the official WooCommerce Marketplace. It handles fingerprint and security key registration with role-based restrictions, and it’s backed by a 30-day money-back guarantee that lowers the risk of trying it. The trade-off is scope: it’s built for account-page login rather than checkout, and the settings run lighter than a purpose-built WooCommerce extension.
Pricing
- 1-year plan: $29
- 2-year plan: $46
Passkey & Passwordless Login Support
- WebAuthn-based login via fingerprint or USB authenticator with no password required
- Integration with the WooCommerce login form; admins can position the button, restrict by user role, and customize the text
- Product updates and improvements
- Customer support
Limitations
- No customer reviews yet listed on the marketplace page
- Account-page login only with no built-in checkout-page placement.
- Configuration options run lighter than a dedicated WooCommerce-first build.
- Requires annual renewal instead of a one-time license.
3. Secure Passkeys
Secure Passkeys is built for WordPress broadly, with MemberPress and WooCommerce support layered on top rather than being the sole focus. Multiple passkeys per user are the standout feature here: a customer can register their phone and laptop separately, which reduces lockouts when they switch devices mid-purchase. The admin panel also gives real visibility into who’s registered what, which helps when support tickets come in about login trouble.
Best for
Stores that combine WooCommerce with a membership plugin and want one login system covering both.
Pricing
Free (no premium tier listed)
Passkey & Passwordless Login Support
- WebAuthn based passwordless login, supports fingerprint, Face ID, and security keys
- Integrates with the default WordPress login, WooCommerce, MemberPress, Easy Digital Downloads, and Ultimate Member
Limitations
- Not purpose-built for WooCommerce checkout placement.
- Support runs through the WordPress.org forum rather than a dedicated ticket system.
- Documentation leans general WordPress rather than WooCommerce-specific.
4. WP-WebAuthn
WP-WebAuthn is the developer’s pick on this list. It brings WebAuthn to WordPress through shortcodes and Gutenberg blocks rather than a polished settings page. It supports usernameless login and works across current browsers, but there’s no dedicated WooCommerce integration out of the box. Checkout placement therefore means custom development work rather than flipping a toggle.
Best for
Developers and agencies building a custom biometric login flow rather than deploying an out-of-box solution.
Pricing
- Plugin: Free (open source, no premium tier or license key)
Passkey & Passwordless Login Support
- Passwordless login using FIDO2 and U2F devices like Passkeys, USB keys, fingerprint scanners, Windows Hello, and Face ID/Touch ID.
- Integrates with default WordPress login. Comes with 4 built-in shortcodes and 4 Gutenberg blocks, including a WebAuthn Login Form block. Beta multisite support
- Usernameless authentication
Limitations
- No dedicated WooCommerce integration; checkout placement needs custom development.
- Support runs through the WordPress.org community forum only with no guaranteed response time.
- Multisite support is still in beta.
- Requires PHP extensions (gmp and mbstring) that not every host enables by default.
5. Multipasskey
Multipasskey, formerly listed as Multidots Passkey Login, runs on FIDO2 and WebAuthn and supports Face ID, Touch ID, Windows Hello, or a device PIN. It’s one of the more actively developed options in this space, with a clean setup flow, though WooCommerce checkout support is listed as coming soon rather than fully shipped.
Best for
Teams planning ahead for WooCommerce passkey support, or agencies managing login across mixed WordPress and WooCommerce properties.
Pricing
Free (no paid tier listed at time of writing)
Passkey & Passwordless Login Support
- Passwordless login via passkeys, supports Touch ID, Face ID, Windows Hello, or device PIN, built on FIDO2/WebAuthn
- Works with existing WordPress accounts, includes shortcodes for login and registration buttons. Compatible with Multisite
Limitations
- WooCommerce-specific checkout support is listed as coming soon and is not fully shipped yet.
- Shorter track record than more established options on this list.
- Documentation is lighter on WooCommerce-specific configuration steps.
6. AwareID
AwareID is the enterprise option on this list. It runs cloud-based biometric authentication instead of a self-hosted plugin. It’s built for regulated eCommerce, online gaming and sweepstakes operators on WooCommerce, and content access control where identity verification matters more than convenience. Setup means registering with Aware and connecting the plugin to their platform. It is not a simple activate-and-go install.
Best for
Larger or regulated WooCommerce operations that need enterprise-grade biometric infrastructure rather than a plug-and-play extension.
Pricing
- Biometric authentication: $50,000/year + $0.05-$0.15/authentication as transaction fee
- WebEnroll licensing starting: $30,000/year
Passkey & Passwordless Login Support
- A modular, works with other systems biometric middleware platform offering automated fingerprint, palmprint, multi-print, and optional face identification.
- Available as stateless REST services (e.g., face similarity, liveness scoring, no data storage) or full managed solutions with duplicate identity prevention via subscription or server-based license.
Limitations
- No self-serve pricing or instant setup; onboarding requires contacting Aware directly.
- Cloud dependency means your login flow relies on Aware’s uptime as well as your own server.
- Overkill for most small to midsize WooCommerce stores without compliance requirements.
Why Do WooCommerce Stores Need Biometric Security?
Password-based login is the weakest point in most WooCommerce stores, and the data shows it.
About 70% of online carts are abandoned, per Baymard Institute research (October 2026). In the same research, 18% of shoppers left because the site wanted them to create an account.
47% of consumers say they are likely to abandon a purchase or sign-in when they cannot remember their password. That figure comes from the FIDO Alliance’s World Passkey Day report of May 2026.
5 billion passkeys are in active use worldwide as of 2026, per the FIDO Alliance’s State of Passkeys report, with 90% consumer awareness. Your customers already use this technology daily. Biometric login on your store meets them where they already are, and closes off one of the more common paths to account takeover in the process.
How to Add a Biometric Verification to Your WooCommerce Store
Once you’ve picked a plugin from the list above, the process looks roughly the same across all six:
- Install and activate: Upload the plugin through your WordPress dashboard, or install it directly from WordPress.org if it’s a free option. Licensed purchases usually come as a zip file to upload manually.
- Open the plugin’s settings tab: Most WooCommerce-focused options add a dedicated tab under WooCommerce → Settings. General WordPress plugins usually add their own top-level settings page instead.
- Choose where the login button appears: Decide between above, below, or alongside the standard login form, and whether it should also show on checkout if the plugin supports that.
- Set role restrictions if needed: Limit biometric login to specific customer groups, like wholesale accounts, if the plugin offers that control.
- Register a test credential: Log in as a test customer and register a fingerprint or face scan. Log out and log back in with it before opening the feature to real customers.
- Confirm HTTPS is active site-wide: WebAuthn won’t fire on an unencrypted page, and this is worth checking before launch rather than after a support ticket comes in.
- Watch registrations for the first few weeks: Most plugins log who’s registered a credential. Use that data to decide whether checkout-page placement is worth adding, if you started with account-only.
Most stores are fully configured within fifteen minutes. The technical setup isn’t the hard part. Deciding where to place the button, and whether your abandonment problem is even login-related, is the decision that matters here.
Conclusion
Biometric login has moved past new idea status. Passwordless authentication now earns higher trust from a growing share of shoppers, and password friction still drives a real slice of cart abandonment. Adding this to your WooCommerce store is a low-risk move with a clear upside, whether you’re running a small storefront or managing checkout for a large catalog.
Our WooCommerce biometric login plugin covers the most ground here, with passkey buttons on My Account, checkout and wp-login.php. It adds recovery codes, staff enforcement and a dashboard that no other plugin in this list offers.
Whichever option you pick from this list, run the checks above first. That’s the step that saves you a reinstall three months from now.
If you’re still weighing whether this is worth doing at all, start smaller than a full rollout. Add biometric login to your account page only. Watch how many customers register a fingerprint or face scan over a month. Then decide whether checkout placement is worth the extra step. The data from your own store will tell you more than any standard in this guide, including this one.
Frequently Asked Questions (FAQs)
Q1. Is biometric login safe for a WooCommerce store?
Yes. The biometric data itself, whether a fingerprint or face scan, never leaves the customer’s device. Your server only stores an encrypted key. That’s why this method is considered more resistant to phishing than passwords.
Q2. Does biometric login replace passwords completely?
Not usually. Most WooCommerce biometric plugins run alongside password login rather than removing it. Customers on unsupported devices or older browsers can still get in the standard way.
Q3. Do these plugins work on mobile?
Yes, and mobile is where they matter most. Typing a password on a phone is slower and more error-prone than tapping a fingerprint sensor. Mobile makes up more than half of eCommerce traffic. This is where the friction shows up most.
Q4. Will a biometric plugin slow down my checkout page?
A well-built one shouldn’t. The scripts involved are small, and the plugin should only load its assets on pages where the login form appears in the first place. Check your page speed before and after activation to confirm nothing changed.
Q5. Can I restrict biometric login to certain user roles?
Most plugins on this list support role-based restrictions, including WooCommerce Biometric Login by DevDiggers and Secure Passkeys. Check the specific plugin’s settings tab. The level of control varies from one to the next.
Q6. What happens if a customer loses the device they registered?
With most plugins here, they log in with their password and register a new device from the account page. WooCommerce Biometric Login by DevDiggers also gives customers ten one-time recovery codes for this case. Keep password login on as a backup for shoppers.
