To confirm you are a human, many websites use a simple test. This involves pressing and holding a specific button or key for a few seconds to prove your humanity. The process typically requires users to tap the “I’m not a bot” checkbox or press and hold a designated key on their keyboard.
This type of system is designed to prevent automated programs, or bots, from accessing a website’s content. By verifying that the user is human, these systems help protect sensitive information and maintain the integrity of online interactions.
The process usually involves a quick test, such as this, followed by an additional verification step if necessary. This may include answering a security question, providing proof of identification, or completing another challenge to confirm your identity as a living being.
