A verification code is a security protection method used by form owners to avoid Internet robots from abusing and spamming their forms. There are different verification code types, but the most commonly used is CAPTCHA. This generates a random code within an image next to a text box. The form visitor has to type in the exact code in order for the form data to be sent. Owners can deactivate the verification code of their web forms. However, this would increase the vulnerability of the forms to spamming attacks. We encourage our form builder users to use verification codes whenever possible on their forms. You can find them in the Security section of the Form Editor, under Captcha settings. [TW] 什麼是驗證碼以及它在表單上的重要性？ 驗證碼是表單所有者用來避免互聯網機器人濫用和發送垃圾表單的一種安全保護方法。 驗證碼有多種類型，但最常用的是 CAPTCHA。 這會在文本框旁邊的圖像內生成一個隨機代碼。 表單訪問者必須輸入準確的代碼才能發送表單數據。 所有者可以停用其 Web 表單的驗證碼。 但是，這會增加表單對垃圾郵件攻擊的脆弱性。 我們鼓勵我們的表單生成器用戶盡可能在他們的表單上使用驗證碼。 您可以在表單編輯器的安全部分的驗證碼設置下找到它們。
