⚡ Captchas

Captchas (from an acronym for "Completely Automated Public Turing test to tell Computers and Humans Apart") are security technologies used to verify whether a user is a human or a bot by presenting challenges that are easy to solve for people but difficult for automated systems.

They use methods such as image and object recognition tasks, text transcription, behavioral analysis, risk scoring, invisible verification, and cryptographic or proof-of-work mechanisms, helping website owners prevent spam, protect forms and accounts, and reduce automated abuse of online services.

According to our research, captcha services are used on 12.5% of all websites.
93.7% of these sites use only one captcha service, 5.2% use two, and 1.1% use three or more simultaneously.
