mojoPortal Tips: Using CAPTCHA in mojoPortal
Written by Carole Bennett Wednesday, 26 September 2012
mojoPortal has implemented many features in order to provide security for its users. One of those features is the CAPTCHA test. We’ll cover a few of the places this can be activated in a mojoPortal site, and ways it can be configured.
For those who aren’t familiar with CAPTCHA: “A CAPTCHA is a type of challenge-response test used in computing as an attempt to ensure that the response is generated by a person. The process usually involves a computer asking a user to complete a simple test which the computer is able to grade. These tests are designed to be easy for a computer to generate, but difficult for a computer to solve, so that if a correct solution is received, it can be presumed to have been entered by a human.” – Wikipedia
One of the first places a mojoPortal user may encounter a CAPTCHA is the registration/login page. The settings to activate CAPTCHA for these areas is located in Administration/Site Settings; you’ll find checkboxes for each option at the bottom of the page under the Security>Main tabs. You can also activate CAPTCHA in the Blog comment areas, by selecting “Enable SPAM blocking” under the Comment System settings.
MojoPortal supports three different versions of CAPTCHA: Simple Math, Subkismet and reCaptcha. These options may be selected under the Site Settings/Security tab.
