Protect against XML-RPC attacks

Author’s Site

1.3.6 – 1 January 2024

Added: Translated language files for French (thanks to Fabrice).

1.3.5 – 20 February 2023

Added: Translated language files for Brazilian Portuguese (thanks to Rodrigo).

1.3.4 – 2 December 2022

Improved: Deletes part of the old data about monthly number of passed or blocked logins so it does not increase the number of options in the database over the years (even though it was an insignificant amount anyway).
Improved: The data about the monthly number of passed or blocked logins is now saved in a way that will avoid automatically loading it in the cached list of options in the server memory, since it is not needed there.

1.3.3 – 11 April 2021

Added: Compatibility with front-end login forms that use the wp_login_form function (but the form must not be cached by a caching plugin).

1.3.2 – 16 December 2020

Added: Translated language files for Polish (thanks to Karol).

1.3.1 – 16 December 2019

Fixed: The language files were not loaded if they were only present in the plugin languages folder (and not in wp-content/languages/plugins).

1.3.0 – 13 December 2019

Added: Compatibility with the WooCommerce login page.
Added: Translated language files for German (thanks to Tilo).
Improved: The gray container of the security code now has a slight border.

1.2.0 – 10 September 2019

Improved: In a multisite, when activated on separate sub-sites only, now uses one global database table.
Fixed: In a multisite, when network activated, it would not work in login pages of separate sub-sites. It would work only on the main site login page, and on the login pages for other site, it would not let anyone in.
Fixed: Changed the label tag surrounding the “Security Code” text, to a span tag. Since there is no field to fill there, it was not correct to use it.

1.1.0 – 4 May 2019

Improved: The correct number is now displayed as a result of a small JavaScript calculation (so not in plain text).
Updated: Language files.

1.0.0 – 11 April 2019

Initial release.

Blocks the ability to login randomly

By hovrashko on May 26, 2023

It does look like nice and simple solution, but it doesn't work and wont login sometimes, or permanently for no reason.

Misses the point! Stupid Plugin

By manikbajaj on May 24, 2023

Really! Lol!! Captcha plugin which can be broken in seconds.

Simple plugin that just works

By Micha (athleticfit) on February 11, 2023

Install and a simple captcha will be displayed in your login. The mass of login attempts by spam robots could easily be reduced with the plugin.
The plugin is not compatible with other plugins such as a login for the user login.
I was able to massively reduce spam attempts by using it. Thank you for the great work!

Locked us out

By DawnK on December 18, 2022

Worked fine at first, but then it ended up locking us out of the site. Entering correct password and the 3 digit code, would say invalid login attempt. Do the Forgot password, change password, and try to login agtain, and it would say invalid login. Had to disable the plugin in order to get access to the site again. Just my experience.

Does add a nice looking simple login code on the login screen. That's it. Works as it should. No upselling, no pro-version, just fullfilling this one usecase. Love it.

Worthless

By neuroticartist on April 21, 2021

Typing in any 3 numbers logs you right in, a waste of time and a false sense of security

Better than hcaptcha and Google Captcha in stopping bots

By tokie001 on December 28, 2020

First of all great job Nikolay for offering this simple yet effective plugin. Deployed this in a few of my clients' sites to conduct A/B testing. Set-up : Usual wp installation with Wordfence to alert login attempts. Login is coursed through the usual wp-login URL. Test 1 : With Google Captcha V2 Activated integrated through Wordfence : 30 days with notification regarding users being locked on in loging in. Tested for 30 Days Test 2 : With hcaptcha installed, same with Test 1. Tested for 30 Days. Test 3: With Simple Login Captcha, No notifications for the past 2 weeks. You may argue that the developer must not use the word captcha . But for me , effectiveness comes first. Will monitor and revise my review if I see any issues.

Simple and effective

By kalor on December 16, 2020

Less is more. Simple plugin, that exactly do what it have to do. Does it save? - YES - if you look for simple, user friendly solution to block automatic bruteforce attacks to wp-login or dummy users registration, and aren't messing with database and UX - NO - if you need real secure mechanism to block attacks designed for your webpage Choose what you need.
