Differences Between reCAPTCHA v2 Invisible, reCAPTCHA v3, and reCAPTCHA v2 Normal

  • reCAPTCHA v2 Normal

    • User Interaction: Requires direct user interaction to verify that the user is human. Users must click a checkbox ("I'm not a robot") and may be asked to solve a challenge (e.g., selecting images).
    • User Experience: More intrusive, as it interrupts the user's flow by requiring them to complete a task.
    • Implementation: Added to a website by including a simple widget, which displays the checkbox for users to click.
  • reCAPTCHA v2 Invisible

    • User Interaction: Does not require the user to click a checkbox or solve a challenge unless suspicious activity is detected. The verification happens in the background.
    • User Experience: Less intrusive, as it typically doesn't interrupt the user's flow. Users might not even notice it unless flagged as suspicious.
    • Implementation: Triggered programmatically on form submission or other actions. Requires adding a badge to the website, often displayed in the corner of the page.
  • reCAPTCHA v3

    • User Interaction: Completely invisible to users. It runs in the background and assigns a score (0.0 to 1.0) based on the likelihood of the user being human.
    • User Experience: Most seamless experience, as there are no interruptions. The score can be used to take action programmatically (e.g., requiring additional verification only if the score is low).
    • Implementation: Integrated into pages where user interactions occur. The site owner decides the threshold score for different actions.
