About this plugin
Rapls Passkey adds passkey sign-in to WordPress. Touch ID, Windows Hello, Face
ID or a security key takes the place of the password, and your server never
holds a shared secret. It stores only a public key, which is useless to anyone
who steals it.
A video walkthrough (in Japanese):
It is built to run where most WordPress sites actually run:
- Fewer moving parts. Nothing to configure before the first passkey, and no gmp to ask your host for: the large-number maths WebAuthn needs uses gmp or bcmath when one is installed and plain PHP when neither is. Signatures are checked with OpenSSL, one of the modules WordPress’s Site Health already looks for.
- Nothing leaves your site. The passkey ceremony happens between the browser and your own server. No account, no API key, no third-party service in the login path.
- Passwords keep working. Password login is never switched off in the free plugin. Nobody gets locked out while a site moves across.
- Japanese UI included. Fully translated, alongside the English source.
What the free plugin does
- Passwordless, phishing-resistant sign-in (WebAuthn / FIDO2)
- Same-device passkeys (Touch ID / Windows Hello / Face ID)
- Cross-device sign-in using the browser’s native passkey flow when the browser offers it (scan with your phone). A custom QR approval flow is available in Pro.
- Shortcodes and Gutenberg blocks (login / passkey management) you can embed on any page
- Rename, suspend and resume individual passkeys — a device that is temporarily out of reach can be cut off without destroying the credential
- A site-wide passkey list for administrators (Users -> Passkeys), searchable by owner or name
- Works with two-factor plugins (Wordfence Login Security, Two-Factor, …): a passkey counts as the second factor, while weaker alternative logins must still pass the site’s 2FA
- An audit log of registrations, sign-ins and removals, exportable as CSV
- WP-CLI commands, a first-run configuration check, and an emergency bypass constant
- Fully translatable UI (English source; translations come from translate.wordpress.org)
Shortcodes
Embed them in any page, post, or widget. In the block editor they are also available as the “Sign in with a passkey” and “Manage passkeys” blocks.
- [rapls_passkey_login] — a passkey sign-in button for logged-out visitors. Supports the redirect (URL to go to after success) and label (button text) attributes.
- [rapls_passkey_register] — a management UI where logged-in users can register and remove their own passkeys.
Requirements
- WordPress 6.0 or later
- PHP 8.2 or later
- HTTPS, except on localhost — browsers refuse WebAuthn without it
No PHP extension beyond WordPress’s own requirements.
Rapls Passkey Pro
Everything above is free, and stays free. Pro is a separate add-on for the part
that comes after the first passkey: moving a whole site across, and keeping a
way in when a device goes missing.
- Sign in from another device — approve a login on your computer from your phone, with a QR code and a four-digit confirmation code so a relayed code cannot be used elsewhere
- A way back in that is not a password — one-time recovery codes and email magic-link sign-in
- Roll out by role — require passkeys for the roles you choose, with a grace period, then turn password login off once everyone is across
- Adaptive step-up — ask for a passkey again after a password sign-in from somewhere unfamiliar
- Authenticator policy — FIDO Metadata Service checks, an AAGUID denylist, trusted-device management
- Operations — security webhooks, adoption reports, multisite network settings, WP-CLI
One-time purchase, no subscription: updates with no time limit, a year of support, and a 14-day refund.

External services
This plugin sends nothing to any external service by default. One optional
integration, off unless you turn it on, contacts a third party:
Google reCAPTCHA v3 — used only when you enable reCAPTCHA for password
logins. When it is on, the visitor’s browser loads
js, and the plugin sends the resulting
token together with the request IP address to
com/recaptcha/api/siteverify so that Google can score the
request. Nothing is sent while the option is off. This service is provided by
Google and its use is governed by Google’s terms and privacy policy:
- Terms of Service: https://policies.google.com/terms
- Privacy Policy: https://policies.google.com/privacy
No other host is contacted. The plugin bundles the public suffix list it needs
dat ) rather than fetching it, and passkey ceremonies
happen between the browser and your own site.
Privacy
Authentication data is stored on your own site.
What is stored:
- Passkey credential records (public key, credential ID, sign counter, a label and timestamps) in a custom database table.
- A per-user WebAuthn user handle in user meta, plus one row in the options table recording that the account has one. The handle carries nothing about the person: for accounts created from this version it is derived from the account id and a site secret, and accounts that already had a random handle keep it.
- An optional audit log of passkey events (registration, sign-in, removal) with the acting user, IP address and timestamp.
Retention and removal:
- Passkey records remain until the user or an administrator deletes them; deleting a user removes their passkey records.
- The plugin integrates with WordPress’s built-in personal-data export and erase tools, so a user’s passkey and audit data are included in export/erase requests.
- Uninstalling the plugin (delete from the Plugins screen) drops its custom table and options.
This plugin does not use cookies for tracking. It sets only short-lived, functional cookies during a login ceremony (for example the pending second-factor login), which expire within minutes.
