CAPTCHA
CAPTCHA stands for the Completely 
Automated Public Turing test to 
tell Computers and Human Apart. 
They are tools you can use to 
differentiate between real users 
and automated users, such as bots. 
CAPTCHAs provide challenges that 
are difficult for computers to 
perform but relatively easy for 
humans. For example, identifying 
stretched letters or numbers, or 
clicking in a specific area.
