Sigil – Passkeys and Two-Factor Authentication

Changelog

0.5.1

• Fixed: after an update, registering a passkey from the front-end page could fail until an administrator opened the dashboard.

0.5.0

• New: sign in with a passkey and no password.
• New: a setup wizard, and you can’t require 2FA for your own role before you’ve set up a method.
• New: remember this device, the WooCommerce My Account tab and the email-code fallback are now free.
• New: limits on wrong passwords, with wp sigil unlock to reopen an account.
• New: import from other two-factor plugins (see the FAQ).
• New: changing a sign-in method, your password or your email asks you to confirm it’s you.
• Improved: password managers can fill authenticator codes, and the two-factor screen works from the keyboard.
• Fixed: front-end password changes no longer sign you out, and the profile screen saves again.
• Sigil Pro is now a separate add-on; install it alongside Sigil and your settings carry over.

0.4.1

• Security: a password alone no longer creates a session before the second step. Please update.
• Security: AJAX login forms no longer accept a password alone from users with a second factor.
• Sign-ins that skip the password (user switching, SSO, magic links) now require the second step. Integrations can call Sigil\Login_Guard::grant().

0.4.0

• Moving from the Two Factor plugin no longer means everyone enrols again. Settings → Sigil and wp sigil import two-factor carry each user’s email codes, authenticator app and backup codes across, so the same authenticator keeps working. Anyone with a method that cannot be carried over is named in the report and stays with Two Factor until they set one up in Sigil. Nobody is moved to email codes they did not already use, and Two Factor’s own data is left as it was.
• While both plugins are active, Two Factor stands down for anyone Sigil already covers, so nobody is asked for a code twice. A notice offers the import until Two Factor is deactivated.
• Security: XML-RPC and REST no longer accept the account password from someone with a second factor. Those requests never reach the two-factor challenge, so a password alone was enough there. Application passwords still work.

0.3.3

• Everyone sharing one address, as an office, a school or a mobile network does, is no longer held to a single person’s allowance of attempts. A few colleagues mistyping could stop everybody else signing in. Guessing any one account is bounded by the same five attempts as before.
• A site behind a proxy can now tell the plugin the real visitor address with the sigil_client_ip filter, instead of counting every visitor as the proxy.
• An account keeps only its newest few unspent verification sessions rather than an unlimited pile of them.
• The allowed-methods screen now says when a role was left with every method because nothing was ticked for it, rather than appearing to have discarded the save.

0.3.2

• A percent sign in the challenge wording no longer breaks the login screen. The line naming the person signing in was formatted rather than substituted, so wording like „50% off“ stopped anybody with a second factor from completing a sign-in.
• An account holding only passkeys is no longer asked for a code when resetting its password. It was being emailed one that could never be accepted, which left the account unrecoverable.
• The two-factor column on the users list now reads each account’s own rules rather than those of the administrator looking at the page, so an account no longer shows as having nothing set up when it has.
• Importing settings now says what happened, including when the imported policy is switched on but names nobody.
• The page carrying the enrolment form is only adopted when an administrator wrote it.

0.3.1

• Repeated login guesses are now counted in a way that a burst of simultaneous requests cannot outrun. The previous counter read a number, added one and wrote it back, so guesses arriving together all read the same number, and the real limit became however many requests could be made at once rather than the five it promised.
• A server that does not report the visitor’s address no longer counts everybody together, where five failures anywhere would have held up every account on the site.
• Failed attempts are cleared out daily instead of being kept indefinitely.
• If the table the counter lives in goes missing, it is rebuilt rather than being allowed to refuse every sign-in.

0.3.0

• You are now emailed when a second factor is added to or removed from your account. Adding one is how somebody who already has your password keeps access, and nothing about the account looks different afterwards, so the only person who can notice is you.
• Anyone who becomes subject to a 2FA requirement is emailed once, when their deadline is set. People who never open the dashboard never saw the notice there, so the first they knew of a policy was the day it stopped them.
• The login code email now says where the code was requested from. It says „may be a proxy“ rather than naming a location, because that is all the server actually knows.
• Administrators are warned when the server clock has drifted far enough to reject correct authenticator codes. Without it, a clock problem looks exactly like every user mistyping at once.
• You can choose which method you are asked for first, if you have set up more than one.

0.2.2

• Adds two extension points: sigil_challenge_text for the wording of the two-factor screen, and sigil_manage_capability for which capability reaches the settings. Values are escaped after filtering, and the capability filter only narrows, never widens.
• Nothing user-facing changed. Existing installs need do nothing.

0.2.1

• Multisite: when an upgrade merges per-site passkey tables, the highest signature counter for each credential is kept. Where the same authenticator was registered on two sites, the lower one could otherwise win and the clone check would have less to work with.
• Adds extension points so an add-on can rewrite the login code email, change where enrolment sends people afterwards, and load the front-end styles outside the shortcode. Nothing in the plugin behaves differently on its own.
• Nothing user-facing changed. Existing installs need do nothing.

0.2.0

• Authenticator setup now shows a scannable QR code. It is drawn in the browser by a bundled MIT-licensed library, so the provisioning secret is never sent anywhere.
• Security: a verification attempt now consumes its challenge token before the code is checked, so a burst of parallel guesses cannot outrun the attempt counter, and two simultaneous completions cannot both start a session. Mistyping a code still lets you try again; the screen carries a fresh token.
• Multisite support. One set of credentials and one policy for the whole network, edited under Network Admin, with rate limiting that counts across sites. Upgrading an existing install carries its policy and passkeys up to network scope.
• Front-end enrolment with the [sigil_2fa] shortcode, for sites whose users have no dashboard access. Enforcement sends people there when the page exists.
• A REST API under sigil/v1 for reading 2FA state, managing methods, editing the policy, and completing a login challenge from a decoupled front end.
• Security: resetting a user’s 2FA treated a missing actor as an exemption rather than as nobody. That was reachable only from the command line before this release, but it is now refused outright, with the unattended path named separately.
• Fixed the enrolment redirect pointing at the wrong admin screen, and the provisioning URI appearing twice during authenticator setup.

0.1.3

• Fixed the two-factor screen at login: it had no stylesheet, so the method switcher rendered as a bare list and the buttons overlapped.
• Fixed passkey sign-in, which could never complete. The browser prompt was requested through an authenticated endpoint the logged-out challenge screen could not reach.
• Email codes are now actually sent when the screen asks for one, and a wrong code no longer invalidates the code already in your inbox.
• A refresh or a second tab no longer invalidates an outstanding passkey prompt.

0.1.2

• Author attribution updated to Jean Galea.

0.1.1

• Renamed the plugin to Sigil. The text domain is now sigil-2fa and the WP-CLI command is wp sigil.
• Translations are no longer bundled; they come from translate.wordpress.org.

0.1.0

• First release: passkeys, authenticator apps, backup codes, and email codes.
• Per-role enforcement with a configurable grace period.
• Lockout recovery: backup codes, admin reset, and a WP-CLI reset command.
• Per-role application-password control.
