An example of captcha when you are registering your account
(an acronym for "C
uring test to tell C
omputers and H
part") is a type of challenge-response test used in computing to determine whether or not the user is human. This form of CAPTCHA requires the user either to select a checkbox which says "I'm not a robot" either select specific squares of a picture based on what is requested. Because the test is administered by a computer, in contrast to the standard Turing test that is administered by a human, a CAPTCHA is sometimes described as a reverse Turing test.
In the previous form of CAPTCHA, the user was required to type the letters of a distorted image, sometimes with the addition of an obscured sequence of letters or digits that appeared on the screen.
The Captcha can occur when you train (usually before the super soldier medal), work (usually before the hard worker medal), send messages, support resistance wars, subscribe newspapers and vote.
Becoming a part of the Loyalty program disables captcha for working, training, sending messages and voting. However, all players still see captcha for every fifth newspaper they subscribe.
