Nowadays, we come across a captcha on almost every website. Every website visitor has to fill in a captcha at signing up or logging in. The websites use a captcha to make it simpler for bots to distinguish between bots and humans.

While robots have difficulty doing tasks, that humans can do so fast. Captcha enables websites to identify bots and block them from accessing their forms by detecting bot activity. You may apply this precautionary action without paying anything because reCAPTCHA provides it as a free service.

The user clicks the link after getting it to check his email and click the verification link. This method aids in confirming that the email is authentic and that a human is attempting to use the system. Any signups that don't finish this step should not be included in your list because it is extremely improbable that a bot will do it.

Ask test questions at login
