Blocks the ability to login randomly

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

Simple plugin that just works

by Micha·3 years ago·1 reply

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·3 years ago·1 reply

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.
