“Captcha” means a test used on websites to check that a real person is using the site, not a bot. It usually asks you to type letters, click pictures, or solve a simple puzzle.
People see captchas when they sign up, log in, post a comment, or submit a form. They help websites block spam and automated abuse, even though they can sometimes be a little annoying.

Examples
You may need to:
- type the letters you see in a distorted image
- click all pictures with traffic lights
- check a box that says “I’m not a robot”
