Accessible CAPTCHA

Why ALTCHA Is the Best Choice for Humans

ALTCHA is redefining CAPTCHA by making it accessible, privacy-friendly, and user-first. Traditional CAPTCHA systems like reCAPTCHA often exclude users with disabilities, frustrate users with slow or confusing challenges, and raise serious privacy concerns. ALTCHA offers a smarter, inclusive solution.

What Is an Accessible CAPTCHA?

An accessible CAPTCHA is one that verifies humans without creating barriers for people with visual, cognitive, or motor impairments. This includes:

• Screen reader compatibility
• Keyboard-only navigation
• Minimal cognitive load
• No reliance on distorted images or audio puzzles

Accessibility is not just a nice-to-have — it’s a requirement for modern, ethical web design. ALTCHA delivers on this by keeping things simple, fast, and inclusive.

Why Most CAPTCHA Systems Fail Accessibility

Popular CAPTCHA solutions often:

• Show blurry or impossible-to-read images
• Rely on mouse interaction or drag-and-drop tasks
• Use audio challenges that are hard to hear or understand
• Time out too quickly or have unclear instructions

These issues exclude millions of users and violate accessibility standards like WCAG (Web Content Accessibility Guidelines). That’s a problem—for your users and for your compliance efforts.

ALTCHA Solves These Problems

ALTCHA was built with accessibility in mind from day one. Here’s how:

• Frictionless:
  ALTCHA uses a simple checkbox or lightweight proof-of-work, making it usable for everyone, including screen reader users.

• Keyboard-friendly:
  Every interaction can be completed using a keyboard alone — no need for mouse gestures or drag-and-drop actions.

• Screen reader support:
  ALTCHA uses semantic HTML and ARIA attributes to ensure full compatibility with assistive technologies.

• No time pressure:
  Users can complete the verification at their own pace. ALTCHA doesn’t lock people out for being too slow.

• Privacy built-in:
  ALTCHA doesn’t track users or store personal data. It respects the rights of every visitor, including those who rely on assistive tech.
