Passwords get reused
A password-only login remains exposed to phishing, reuse and leaks.
Why passkeys
Customer login should protect without slowing people down
Passwords create risk and friction. Passkeys connect stronger account protection with a familiar device confirmation.
Reset flows interrupt
Forgotten passwords send returning customers through an avoidable recovery loop.
The device is already there
Passkeys use the screen lock customers already know from their phone or computer.
Passkeys in 45 seconds
A login secret that never has to leave the device
A passkey uses a cryptographic key pair. The private key stays on the user's device or in their passkey manager. Your login only receives a signed proof for the real domain, not a password that could be entered on a phishing page.
What does “synced passkey” mean?
A passkey manager can make the passkey available on the customer's other devices, making it particularly useful for consumer accounts.

Benefits
One change, two perspectives
For the shop
- Stronger protection against phishing-based account takeover.
- No password as the primary login secret to store or reset.
- Standards-based integration through WebAuthn and OIDC.
- Introduce passkeys alongside existing sign-in methods.
For customers
- Sign in with the familiar device screen lock.
- No shop password to remember or reuse.
- Phishing-resistant confirmation for the real domain.
- Synced passkeys can be available across multiple devices.
Effects on support effort or conversion depend on the actual rollout and are not guaranteed.
Three paths
You do not automatically need your own passkey server
The right path depends on your shop platform, technical capacity and desired level of control.
Native feature or extension
Use a maintained passkey capability in your shop system or a suitable extension.
- Potentially the shortest setup
- Check account migration and recovery
- Review update ownership and platform lock-in
Managed identity service
Connect a managed provider over OIDC instead of operating the passkey infrastructure yourself.
- WebAuthn logic and updates are operated for you
- Good fit for small teams with OIDC support
- Check hosting, export, branding and pricing
Own implementation or self-hosting
Build or operate the passkey layer yourself when deep control justifies permanent ownership.
- Highest design freedom
- Requires security and identity expertise
- Operations, monitoring and recovery stay with you
Your platform has a maintained passkey featureSuitable path: Native feature or extension
Small team, OIDC available, no identity operations desiredSuitable path: Managed identity service
Dedicated identity team and special requirementsSuitable path: Own implementation or self-hosting
Rollout
Introduce passkeys without a big bang
Start alongside the existing login, learn from a pilot and only tighten the policy once migration and recovery work reliably.
Take inventory
Map platforms, login flows, customer accounts and dependencies.
Choose a path
Balance effort, control, operations and migration.
Run a pilot
Start optionally with a small, observable customer group.
Guide customers
Explain registration, device changes and recovery clearly.
Secure operations
Keep updates, monitoring, support and fallback under review.
Customer guidance
A secure login still needs understandable UX
The technical integration is only half the work. Registration, fallback and recovery must remain clear on mobile and desktop.
- Use a clear and consistent “Sign in with a passkey” label.
- Explain the benefit before asking customers to create a passkey.
- Link existing accounts unambiguously and avoid duplicate accounts.
- Keep fallback and recovery findable without making them the default path.
- Plan for device changes, lost devices and multiple passkeys.
- Test mobile, desktop, browser changes and the return to checkout.
Tools for your rollout
From orientation to a reliable launch
These practical helpers are in preparation. Their cards stay in place and become direct tools as they launch.

FAQ
Passkeys for online shops: common questions
No. A native shop feature, a maintained extension or a managed identity service can provide passkeys without your team operating its own passkey server. The right option depends on your platform and control requirements.
Usually yes, but the linking rule must be planned carefully. Existing accounts may be linked through a verified email address or a stable OIDC subject. Test collision, duplicate-account and recovery cases before rollout.
Synced passkeys may already be available on another device through the customer's passkey manager. You still need a secure recovery path and should allow customers to register more than one passkey.
Yes. A gradual rollout is often the practical starting point. Offer passkeys optionally, observe registration and recovery, and only change the default or policy after the flow is reliable.
Tuurio ID connects through standard OpenID Connect. Existing integration pages cover WordPress and PrestaShop; other platforms require a suitable OIDC client or adapter.
WebAuthn is the browser API used for public-key credentials. FIDO2 combines WebAuthn with the authenticator protocol. A passkey is a user-friendly WebAuthn credential that can be device-bound or synchronized.
Not exactly. A passkey can provide strong, phishing-resistant authentication with device possession and local user verification, but the assurance and policy depend on the authenticator and your implementation.
Plan security updates, monitoring, support, account recovery, fallback methods, credential management and a migration or export path. These responsibilities remain relevant even with a managed provider.
Sources and review
Technical foundation: BSI TR-03188, WebAuthn and FIDO
BSI TR-03188 describes security recommendations for passkey servers and is especially relevant to own implementations and self-hosting. For platform features and managed services, selection, migration, recovery and operational responsibilities still need to be assessed. WebAuthn and FIDO provide the underlying technical framework.
