Description

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.

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

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!

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.

Journal

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
