Deskripsyon
Defyn Security Manager is a lightweight WordPress security plugin that hides your login page and locks down the back end. Most attacks on WordPress start at one predictable place: /wp-admin and /wp-login.php. Defyn Security Manager moves that door, throttles attackers, adds two-factor authentication, and records every attempt so you always know who is knocking.
No bloat, no upsell walls, and no account required. Install it, choose a secret login slug, and your login page disappears from bots and scanners.
What it does
- Hide the WordPress login URL. Replace
/wp-adminand/wp-login.phpwith any custom login URL you choose, so automated bots and brute-force scripts hit a dead end. - Decoy or 404 the old URLs. Decide what attackers see at the original login addresses: a 404, a redirect, or a decoy login screen.
- Brute-force protection. Limit login attempts and automatically lock out IP addresses after repeated failures, with a one-click control to clear active lockouts.
- Two-factor authentication (2FA). Add TOTP-based two-factor authentication using Google Authenticator, Authy, 1Password, Microsoft Authenticator or Bitwarden, complete with backup codes and per-role enforcement.
- REST API and XML-RPC protection. Extend two-factor enforcement to the REST API and XML-RPC, with optional API hiding to shrink your attack surface.
- Time-window access control. Only allow logins during the hours and days you actually work, and block everything else.
- IP allowlisting. Optionally restrict back-end access to trusted IP addresses or CIDR ranges.
- Activity log and audit trail. See login attempts, lockouts, scans of your old login URLs, and settings changes in one searchable log.
- Email alerts. Get notified about lockouts, scans, and logins from new IP addresses.
Why choose Defyn Security Manager
- Fast and focused. A purpose-built login-security and login-hardening plugin, not a heavyweight suite that slows your site down.
- Recovery built in. A documented emergency kill switch means you can never permanently lock yourself out.
- Privacy friendly. Your data stays on your site. Nothing is sent to a third-party service.
- Built by an agency. Maintained by Defyn, an Australian web design and development studio that runs this plugin on client sites every day.
Defyn Security Manager is ideal for anyone who wants to hide wp-admin, stop brute-force login attempts, limit login attempts, add 2FA to WordPress, and keep a clear security audit trail.
Pag-install
- In your dashboard, go to Plugins, Add New, search for “Defyn Security Manager”, then click Install Now and Activate. You can also upload the plugin folder to
/wp-content/plugins/via SFTP. - Go to Defyn Security, Settings and set your custom hidden login URL.
- Choose what visitors see at the old
/wp-adminand/wp-login.phpaddresses, then turn on brute-force throttling, time-window access, or IP allowlisting as needed. - Open the Two-Factor tab to enable 2FA and, if you want, enforce it per role.
- Bookmark your new login URL and store your 2FA backup codes somewhere safe before you log out.
FAQ
-
How do I hide the WordPress login page?
-
Activate the plugin, open Defyn Security, Settings, and enter a custom slug for your login URL. From then on your login page lives at that secret address, and
/wp-adminand/wp-login.phpreturn a 404, a redirect, or a decoy screen, whichever you choose. -
I have locked myself out. How do I recover?
-
The fastest fix is to add this line to
wp-config.php:define( 'DEFYN_BEM_DISABLE', true );This bypasses all login interception so
/wp-adminand/wp-login.phpwork normally again. A yellow admin notice reminds you to remove the line once you are back in. Your settings and 2FA data are kept.If you cannot edit
wp-config.php, rename the plugin folder over SFTP fromdefyn-security-managertodefyn-security-manager.disabled. WordPress deactivates the plugin on the next page load. Rename it back when you are ready to re-enable. -
Does it work behind Cloudflare or a load balancer?
-
Yes. Define
DEFYN_BEM_TRUST_PROXYinwp-config.phpso the plugin honoursX-Forwarded-ForandCF-Connecting-IPheaders when detecting the visitor IP address. -
Which authenticator apps work with the 2FA feature?
-
Any app that supports standard RFC 6238 TOTP, including Google Authenticator, Authy, 1Password, Microsoft Authenticator and Bitwarden.
-
Will hiding the login URL break my site or REST API?
-
No. Front-end pages, the REST API and normal site behaviour keep working. Only the human login entry points move, and you can layer two-factor enforcement on top of the REST API and XML-RPC separately.
-
Does it slow down my website?
-
No. The plugin only runs its checks on login and admin requests, so it has no measurable impact on front-end page speed.
-
Can I use it on a multisite network?
-
This release supports single-site activation only. Network-wide multisite support is on the roadmap.
