Is it possible to automate captcha?

Yes, captcha can get automated. But the restriction is that only those captchas would be automated which are our own but not from other tools.

For example, an organization has a captcha on its web page, so someone has to tick that captcha, but it is not possible to check all the captcha at the same time for a manual tester. So it’s better to automate the captcha in the pre-live environment, say, Development or QA environment by getting the captcha answer in some attribute of the element, after that we need to enter the value to the input field, which accepts captcha value. We also need to make sure to remove this attribute while pushing the code to the Live environment.
