Captcha

The Captcha component distinguishes humans from bots by presenting a challenge that is difficult for computer programs.

Usage Guidelines

The Telerik and Kendo UI Captcha requires you to follow some basic principles when using the component.

Placeholder Text

The importance of using clear and descriptive text in the Captcha input field cannot be overstated. By providing users with clear guidance and explanations, you help them interact with the component more smoothly and efficiently. This not only improves the user experience but also reduces the chance of errors or frustration that can arise from unclear instructions.

Use descriptive and clear placeholder text in the Captcha input field to provide users guidance on what to do.
А Telerik and Kendo UI Captcha without placeholder text
Avoid omitting or using vague placeholder text in the Captcha input field, as it can confuse users and make the required action unclear.

Audio Alternative

When using the Captcha component, it's important to implement an audio alternative aimed at users with visual impairments. In this way, you provide user-friendly and inclusive access to your content. With the audio alternative, you can ensure that all users, regardless of their abilities, can access and use your applications.
