Beschreibung

A simple captcha for the WordPress login form. To be able to login, the user is required to enter a random 3-digit number in a text field.

The correct number is displayed above the field by a small JavaScript code. Compatible with the WooCommerce login form. Compatible with multisite.

Recommendation

Bots can also try to login with the XML-RPC feature of WordPress! Very rarely plugins also need this (like the Jetpack plugin). But if you don’t use it, I recommend that you disable it. You can use the super simple one-line plugin Disable XML-RPC.

Notice

This is a simple plugin designed to protect against random bots that try to login on your site. But if a person actually looks at the code of this plugin and specifically designs a new bot that targets this plugin, this bot would be able to bypass the protection.

How to deactivate the plugin if it does not allow me to login due to an error?: If there is an error or a bug, and you are locked out of the site by this plugin, you can simply delete or rename the plugin folder /wp-content/plugins/simple-login-captcha/ using FTP or the file manager of your hosting.

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.

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

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.

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.

Änderungsprotokoll

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.

Great plugin

Perfect. Simple. Looks good. Effective.
