How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price.

    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.

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