説明

FluentAuth is a login security plugin for WordPress. It protects the way people sign in to your site, and it tells you when something on your site has changed.

You get two-factor authentication, passkeys, social login, magic login links, login attempt limits, IP access rules, a security checklist, file change scanning and a full audit log. All of it in one plugin, with no bloat and no slowdown.

Two-Factor Authentication (2FA)

Ask for a second step after the password. Three ways to do it, and you choose which roles may use each one.

Email codes. A one time code sent to the user’s inbox. Nothing to install.
Authenticator app. Google Authenticator, Authy, 1Password or any other TOTP app. FluentAuth draws the QR code on your own server, so the secret never leaves your site.
Passkeys. Touch ID, Face ID, Windows Hello, a hardware security key or a password manager. The browser ties the passkey to your domain, so it cannot be used on a fake copy of your login page.

You can let a role set up a second factor or require it, and you choose how strong a required one has to be: a device factor only, meaning a passkey or an authenticator app, or any of the three. Anyone who must have one sets it up while they sign in, before a session is created for them, so the requirement cannot be walked past.

An authenticator app also hands out ten single use recovery codes, and passkey users can fall back on those too. Everyone manages their own second factor from their WordPress profile screen, and an admin screen lists who has enrolled, what each person registered, and lets you reset anyone locked out.

Authenticator secrets can be encrypted in your database with a key you keep in wp-config.php, so reading the database gets an attacker nothing.

Passkey Login

Passkeys are the strongest option here. The credential lives on the device and is bound to your domain by the browser, so phishing does not work against it: a copied login page has a different domain and the passkey will not answer.

They can be the second step after a password, or the way in on their own – turn on passkey sign-in and the login form offers a button that signs the user in with no password at all. No third party service is involved: everything runs on your site.

Social Login and Registration

Let people sign in with the accounts they already have.

Login with Google
Login with GitHub
Login with Facebook
Google One Tap Login

Turn on the providers you want, paste the keys, and the buttons appear on your login and register forms. You can also stop social sign ups when registration is closed on your site.

Magic Login by Email

Users type their email address and get a one time login link. No password to remember and no reset flow to walk through. Make it the main way people sign in, or keep it as an extra option. Links are hashed, expire, are rate limited and can only be claimed once, and asking for a link never reveals whether an address has an account on your site.

Limit Login Attempts

Block brute force attacks by counting failed logins. Set how many attempts are allowed and over how many minutes, and FluentAuth locks the address out for a while. Every blocked attempt is logged, and you can be emailed when it happens.

IP Allow List and Block List

Two simple lists, one address or range per line. The block list refuses a login from those addresses outright. The allow list skips the attempt limit for addresses you trust, such as your office.

You can also require that a role only signs in from an allow listed address. FluentAuth detects reverse proxies and Cloudflare, so the address it acts on is the real visitor address and not your proxy.

Security Checklist

FluentAuth checks your site and gives you a short list of what to look at. Each item says what is wrong, why it matters and what happens if you fix it, and most have a button that fixes it for you. Anything that does not apply can be waved away, and you can take that back later. It checks things like:

HTTPS, and PHP errors shown to visitors
Theme and plugin file editing from the dashboard
The security constants in wp-config.php
Old backup files sitting in a public folder
PHP execution inside your uploads folder
Drop-in or mu-plugin files that have appeared or changed
Administrators with an easily guessed username, or gone unused
User accounts that do not show on the users screen

File Change Scanning

FluentAuth compares your files against the official copies published on WordPress.org.

WordPress core files, against the official checksums for your version.
Plugins from the WordPress.org directory, against the checksums for the version you have installed.
Themes from the WordPress.org directory, against the official theme package, since themes have no published checksums. Needs the ZipArchive PHP extension, which most hosts have.
Files nothing else can verify, such as a custom theme or a premium plugin, recorded in a snapshot so you hear about it when one changes.

When a file has changed you can see a side by side diff against the original, put the original back with one click, or delete a file that should not be there. You can also flag a plugin or theme running a version that was never published, a common sign that files were swapped out.

Activity and Audit Logs

FluentAuth records every login, failed attempt and blocked address, and every plugin or theme activated, deactivated or updated, with who did it. Logs go in their own database tables, so your WordPress tables stay clean, and old entries are cleared on a schedule you pick.

Email Notifications and Reports

Get an email when an administrator or editor signs in, or when someone is blocked for too many failed attempts. You can also get a daily, weekly or monthly summary of what happened on your site.

Recovery Tools

If you think somebody has been in your site, one screen tells you what to do next.

Sign everyone out and revoke every application password
Send password reset emails to your users, in batches so nothing times out
Reinstall WordPress core from the official copy
Reinstall a plugin or theme from the WordPress.org directory
Rotate the security keys in wp-config.php, with a clear warning about what else that breaks

Everything done here is written to the audit log with the name of the person who did it.

Login Redirects

Send users to different pages after they log in or log out, based on their role. Set it up once and it applies to every login method, including social and magic login.

Login and Signup Page Customizer

Set your own logo, colours, background and form style on the WordPress login page, and see the result as you edit. You can also build login and registration forms anywhere on your site with shortcodes.

Custom WordPress System Emails

WordPress sends a lot of plain default emails. FluentAuth lets you rewrite them with your own wording and branding, and gives you one template design they all share. You can also turn off the admin notification that fires every time a new user signs up.

Core Security Hardening

Turn off the parts of WordPress your site does not use.

Disable XML-RPC
Disable application passwords and remote app login
Stop user listings being read through the REST API
Restrict /wp-admin for low level roles
Hide the admin bar for the roles you choose

Remote Auth for Multiple Sites

Use one site as the login provider for your other sites. Users sign in once on the main site and land on the child site already logged in.

Guided Setup

A short setup wizard runs the first time you open FluentAuth. It asks a handful of questions, shows you what each answer changes, and turns on a sensible set of options. Skip it and nothing is written, and every answer is an ordinary setting you can change later.

Built to Be Fast

FluentAuth is one plugin doing the work of several, written to stay out of the way. The admin area is a single page Vue 3 app over the REST API, logs live in custom database tables, and no scanning agent sits in front of every request on your site.

For Developers

Another plugin can put its own login screen on FluentAuth’s flows. It registers with the LoginBridge service, and from then on its custom form gets the attempt limits, the IP rules and the two-factor challenge, including an inline second step on a custom AJAX action. There are filters through the whole auth flow, and the site owner’s settings always win over what an adopting plugin asks for.

External Services

Nothing below leaves your site unless you turn that feature on.

File scanning compares your files against the official copies, so it fetches them from WordPress.org (api.wordpress.org, downloads.wordpress.org, plugins.svn.wordpress.org, themes.svn.wordpress.org) and the official WordPress mirror on GitHub (raw.githubusercontent.com). Only the name, version and file path of the item being checked is sent. WordPress.org privacy · GitHub terms and privacy.
FluentAuth Alerts Service (dash.fluentauth.com, run by WPManageNinja LLC) sends you scheduled scan alerts by email. Off until you connect it, and the screen lists what would be sent – your name and email, your site address and title, the paths of files that differ, and your plugin and theme versions – before you decide. Never file contents, database data, or anything about your visitors. Privacy · Terms.
Social login contacts Google, GitHub or Facebook only if you set one up, and only when a user clicks the button: the standard OAuth handshake plus the user’s name and email so the account can be matched. Google (terms, privacy) · GitHub (terms, privacy) · Facebook (terms, privacy).

Why FluentAuth?

Most WordPress sites get broken into the same way. Somebody guesses a password, or reuses one that leaked somewhere else, and walks in through the login form. The login form is the door, and that is what FluentAuth guards.

Running several security plugins to cover this is its own problem. Each one hooks into every request and runs its own set of rules, and the site gets slower for it. One plugin that covers login security, two-factor authentication, social login, file scanning and audit logs is less work for your server and less work for you.

That is why we built FluentAuth, and that is why it is free.

FAQ

Is FluentAuth free?

Yes. Every feature described here is free. There is no paid version and no locked screens.

Does it slow my site down?

No. FluentAuth does not sit in front of every request the way a firewall plugin does. Logs are kept in their own database tables, so your WordPress tables stay small, and the admin area is a single page app that loads once.

Does two-factor authentication work with Google Authenticator?

Yes. The authenticator app option works with Google Authenticator, Authy, Microsoft Authenticator, 1Password, Bitwarden and any other app that supports TOTP.

What is a passkey?

A passkey lets someone sign in with Touch ID, Face ID, Windows Hello, a hardware security key or a password manager instead of typing a code. The browser ties it to your site’s domain, so it cannot be used on a fake copy of your login page. FluentAuth supports passkeys as a second factor, and as a way to sign in on their own with no password at all.

Can I force two-factor authentication for administrators?

Yes. You can pick which roles may set up a second factor and which roles must have one. A user who must have one is asked to set it up while they sign in, before a session is created for them, so the requirement cannot be walked past by going straight to a page that is not the login form. You can also say how strong that factor has to be: a device factor only, meaning a passkey or an authenticator app, or any of the three including an emailed code.

Do I have to connect to an external service?

No. Two-factor authentication, passkeys, audit logs, login limits and the rest all run on your own site.

Two things do reach out. Scanning asks WordPress.org for the official copy of your files, which is how it can tell whether a file changed, and it sends nothing about your site to do that. And there is an optional FluentAuth Alerts Service that handles scheduled scans and alert emails. It is off until you connect it, and the screen lists what would be sent before you decide. See the External Services section above.

Is it GDPR compliant?

Yes. All of your data stays in your WordPress database unless you choose to connect the optional alerts service, and what that sends is listed above in the External Services section.

Does it work with WooCommerce and membership plugins?

Yes. FluentAuth works on the standard WordPress login, so it covers logins from WooCommerce, LearnDash, membership plugins and custom login forms.

Can I use it on a multisite install?

Yes. FluentAuth runs per site on a multisite install, and it is aware of multisite when it decides whether a user may sign in to a given site. There is no network wide settings screen, so each site is configured on its own.

What happens if I lock myself out?

Use one of the recovery codes you were given when you set up your authenticator app. If you have lost those too, another administrator can reset your second factor from the 2FA Enrollment screen.

If you are the only administrator and everything is gone, add define('FLUENT_AUTH_DISABLE_TWO_FA', true); to your wp-config.php and the second factor is lifted for the whole site. Put a username in place of true to lift it for that one account only. Take the line out once you are back in. While it is there the login screen says so, the dashboard warns you, and every sign-in that used it is written to the audit log.

Does the file scanner remove malware?

It is not a malware scanner. It tells you which files no longer match the official copy published on WordPress.org, shows you what changed, and lets you put the original back. That catches the file changes an attacker leaves behind, and it does it without a signature list to keep up to date.

I've had my eye on this plugin for a while, but didn't fully implement it until I learned that version 3.0 supported both passkeys and 2FA with authenticator apps. Between that and email verification codes upon registration, this plugin goes a long way to making authorization on your WordPress site much more secure. It even has other cool features like a login page customizer and file monitoring. In an era where AI is fasttracking the discovery and exploitation of any little software vulnerability, every bit of security you can add to your site is important. There are only two other features that I wish it had: 1) Built-in Cloudflare Turnstile protection for the login/registration form (but that's easy enough to add with another plugin or custom dev); 2) the option to change the URL/slug of the login page (like the WPS Hide Login plugin). Even with those two features lacking, though, this plugin is now an easy 5-star plugin in my book. I'd recommend it for any WordPress site.

This is a great plugin. Even better has been the support I have received from the team.

richard0508 2026年6月21日

There is no way to customize the login and registration fields. Even when using the provided shortcuts, these pages still cannot be customized as needed. The documentation is so brief that it is difficult to find any truly useful information. After integrating Google Sign-In and Google Registration, users who register with a Google account get stuck on the login page and are never redirected, making the registration process unusable. FluentAuth customer service team didn't solve my problem at all. They spent two whole weeks repeatedly telling me that I was just stuck on the login issue, which was a complete waste of my time. In the end, I had to fix it myself. The actual issue was that after completing the registration, the page cache got completely stuck and failed to pass the data to the account login. This caused an infinite loop on the login page, making it absolutely impossible to log in. This is clearly a flaw in your system's design and has absolutely nothing to do with any third-party plugins.

Fluent Auth / Fluent Security is a nice security plugin with all the most important security features, but without the unecessary and the bloat

gfa7 2026年3月23日

Got superior support for resolving a conflict and finding issues in somebody else's code. Thanks again!

unknowncreative 2025年12月11日

Over all it works and does a dam good jobonly current complaint/bug, is that login with google still requires a code to be sent and entered.Hope to see this plugin for years and years to come

変更履歴

3.0.3 – Date: Sep 20, 2026

Added compatibility with MainWP and other plugins that sign users in programmatically. These sign ins are now recorded in the audit log as a programmatic login, collapsed into one entry per hour, and do not send a login notification email.
Fix: Signing in with Google One Tap or a passkey on a site that asks for a second factor now takes you to that step, instead of showing an error with no way forward.
Fix: Answering a second factor after signing in with a social account now returns you to the page you started from.
Improved user facing strings and error messages throughout.
The recovery help on the two-factor login screen now appears after 50 seconds.

3.0.2 – Date: Sep 18, 2026

Fix: Requiring two-factor no longer locks anybody out of wp-admin, or breaks front-end forms and add-to-cart for logged-in members.
Fix: Sites in other languages no longer report a WordPress core file as changed on every scan.
Fix: Recovery codes are shown only to the person they belong to, and setting up an authenticator app no longer replaces codes you have already saved.
Fix: Passkey setup on sites that use passkeys without authenticator apps, including retrying a prompt the server refused.
New: Tells you when another plugin is also enforcing two-factor login, since two of them cannot both finish a sign-in.
Improvement: Says when a scan could not reach WordPress.org, instead of going quiet.

3.0.1 – Date: Sep 17, 2026

Fix: Setup wizard switches could not be turned off.
Fix: Two-factor requirements now follow the method switches – a method that is off is off for everybody. Sites updating from 3.0.0 that required a factor with every method off keep working: the authenticator app is switched on for them automatically.
Fix: The dashboard reported two-factor as off on sites using passkeys without authenticator apps.
Fix: The login page designer can now edit the sign-in form’s own colours, and from name and reply-to apply to every email FluentAuth sends.
Improvement: Plain-language rewrite of the admin screens, plus fixes to activity log search, the encryption panel and sign-ins through third-party login forms.

3.0.0 – Date: Sep 16, 2026

New: Two-factor authentication with passkeys, authenticator apps and email codes. Pick which roles may set one up and which must have one, and how strong a required factor has to be. A required factor is now enrolled during sign-in, before a session is created, and everyone manages their own from their WordPress profile screen. Ten recovery codes come with every authenticator setup, stored secrets can be encrypted with a key in wp-config.php, and an emergency bypass constant is there for the day somebody locks themselves out.
New: Passkey sign-in with no password at all, offered on the login form beside magic links and social login.
New: Security checklist that tells you what to fix and fixes most of it for you, covering HTTPS, debug output, the file editor, wp-config constants, backup files, uploads folder execution, drop-ins, mu-plugins, admin usernames, dormant admins and hidden users.
New: File change scanning for WordPress core, and for plugins and themes from the WordPress.org directory, with a side by side diff, a one click restore, and baseline snapshots for the files nothing else can verify.
New: Recovery tools for a site that has been broken into – sign everyone out, revoke application passwords, batched password resets, core and extension reinstall, and optional salt rotation, each one written to the audit log.
New: IP allow and block lists with a role restriction, real visitor IP detection behind a reverse proxy or Cloudflare, activity logging for plugin and theme changes, a guided setup wizard, and a LoginBridge service so another plugin can run its own login screen on FluentAuth’s flows.
Improved: Settings rebuilt around a sidebar and the admin UI refreshed throughout, with hardening across login attempts, magic login, social login, email smart codes and the alerts service – plus fixes for two-factor enrollment counts, dark mode, small screen layout and the password reset email link.

2.1.2 – Date: Apr 28, 2026

Hardened Security Scan and Settings endpoints with stricter input validation and sanitization
Sanitized social auth redirect cookie to prevent storing untrusted values
Added client token verification in Google One-Tap login for stronger identity checks
Fixed: Magic Login rate limiter incorrectly using days instead of minutes
Fixed: Login issue with GitHub social authentication
Fixed: Timezone mismatch in dashboard quick stats and audit log time differences
Fixed: canLogin filter ignoring falsy return values (now respects developer overrides)
Fixed: Sprintf positional argument syntax in digest email and removed a duplicate filter
Improved: Translation readiness: wrapped previously hard-coded admin UI strings with the translation helper and fixed typos / awkward phrasing across the dashboard, settings, security scan, server mode, and email customization screens
Improved: Internal test coverage and codebase reliability
