‘Completely Automated Public Turing test to tell Computers and Humans Apart’ or CAPTCHA is a real test that helps determine if a user is human. In short, this challenge can only be solved by a human, and this assessment alone can distinguish a machine from a human in computing.
It is used to crack lost passwords, register online, and set up email accounts, against privacy violations and spam. It can protect a website from unwanted bots from the internet. Of course, this way, it ensures that the whole system is free of any damage and that it runs suitably without much difficulty.
More on CAPTCHA
The term CAPTCHA was first coined by John Langford from IBM along with Nicholas J. Hopper, Manuel Blum, and Luis von Ahn of Carnegie Mellon University. Sometimes CAPTCHA is designed with letters in a distorted form, puzzles, pictures, and numbers. The most interesting part about this test is that a computer evaluates the test, which is why it is also known as the reverse Turing test.

Awesome Article! I’ve been very impressed with your articles so far. I know it has been a few weeks since you originally posted this, but I haven’t had time to comment. I have a question I’ve been trying to find the answer for and I was hoping you might have some insight. I’m considering investing in backupbuddy or updraftplus. They are similarly priced, but I can’t see a clear winner. Any insight would be greatly appreciated! Also, I’ve heard some criticize anything back-up plugins besides vaultpress because theoretically a hacker could just mess with your plugin once they are in your site. I’m still leaning towards backupbuddy or updraftplus for the economic advantages.
First of all thank you for posting. The plugin I am looking for is the one you are having on your website. Could you please let me know what plugin are you using.???
Regards
I don’t know why, but none of them working for me, maybe issue is in theme or something

Don’t use SweetCaptcha — it is now distributing malware.
Hey Jeremy would you like to share any insights on this , any proofs ?
One of my clients websites was infected by malware delivered by Sweet Captcha. She lost a few potential clients (who thankfully told her about the malware popups) and narrowly escaped being blacklisted by Google. Since she heavily relies on great Google positions this could have totally destroyed her business.
DON’T INSTALL SWEET CAPTCHA
