CAPTCHA stands for "Completely Automated Public Turing test to tell Computers and Humans Apart". These tests are used to ensure that your site is not subjected to automated attacks/spam from bots attempting to register or log in to your site. Customers must enter the text seen in the CAPTCHA image (which computers cannot read) before they can log in:
The CAPTCHA image can be enabled on 3 pages, using the following Settings:
Setting Name
Page
SecurityCodeRequiredOnAdminLogin
admin/signin.aspx
SecurityCodeRequiredOnCreateAccount
createaccount.aspx (?checkout=false)
SecurityCodeRequiredOnCreateAccountDuringCheckout
createaccount.aspx (?checkout=true)
SecurityCodeRequiredOnStoreLogin
signin.aspx
The CAPTCHA image can be customized according to the requirements/desires of your site, using the following Settings:
Setting Name
Description
Captcha.AllowedCharactersRegex
This is a regular expression which determines which characters the CAPTCHA image will contain.Do not change this if you are not familiar with regular expressions!
Captcha.CaseSensitive
Setting this to true will require customers to properly match the case shown in the CAPTCHA image.Setting this to false does NOT make the CAPTCHA image not use caps in the image, it simply ignores the case for the customer entry. Disabling caps entirely would require editing the Captcha.AllowedCharactersRegex AppConfig.
