The goal of the security image is to prevent computerized search and spam engines from generating fake emails or logins. In theory, people can read the images and enter the site, while computers are unable to decipher the images. If you are unable to read the letters, you can click the listening icon to hear the letters.
Currently all security images on this website only display capital letters and are generated completely randomly. No numbers are used in the images. You can type in your letters in capital or lowercase letters.
Note that if you can not read the image, you can refresh the browser to generate another image.
