Hello guys, I know a lot of us has seen a recaptcha, but I would like to enlighten you a little bit on it.
What is a "RECAPTCHA"
A recaptcha is a free service that has been produced by Google to distinguish a human from a bot.
A recaptcha can also be seen as a Google service that helps to protect a site from spam.
How does it work?
Most of the time, a recaptcha appears like a friendly image. One is being given certain instructions to carry out of which they know a bot cannot do. Failure to pass a recaptcha leads to inability to proceed in any process.
