| − | As bots and software have become more sophisticated, a common solution was to make the text more difficult to read, which can result in frustrated and lost potential clients.

By using an advanced and more secure risk analysis engine, humans and bots are more effectively differentiated.

| − | The first step in authentication is to ask the user to confirm that they are not a robot by ticking a checkbox. While this sounds simple, Google's risk analysis engine takes a lot into account about how the user came to tick the checkbox, including how the user responds before, during, and after the action. In cases where the engine cannot confidently differentiate, a mobile-friendly verification tool like image selection from a list may be supplied or a CAPTCHA itself.
