====== 7.5.2. Provide a refresh method for each CAPTCHA ======

For each CAPTCHA (anti-spam system), a way for refreshing the content must be provided, because the user is often unable to decipher the CAPTCHA at the first attempt. 

<note astuce>**Tip**\\
A good practice is to propose, in addition to the refresh solution, a way of contacting the website administrator in the event that the CAPTCHA value cannot be entered (link to a “Contact” page, telephone number, etc.).
