Google's "No CAPTCHA reCAPTCHA" is a new way to show a CAPTCHA challenge to your users. In this type of CAPTCHA, instead of asking the user to type a series of letters or numbers, they are asked to click on a specific area in a image. This image contains a sequence of numbers or letters which can be read by a computer. The user's click is used to confirm that they are not a robot.
There are a few different ways that this CAPTCHA can be used. One is to have the user click on a specific area of an image. Another is to have the user select all of the images that contain a specific object. This object can be anything, such as a cat, a tree, or a building.
The CAPTCHA can also be used to ask the user to select all of the images that contain a specific word. This word can be anything, such as "cat", "tree", or "building".
No CAPTCHA reCAPTCHAs are very effective at preventing bots from spamming your website. They are also very easy for humans to solve. This makes them a great option for websites that want to prevent bots from spamming, but still want to allow humans easy access.
