Slider Verify – Simple and Elegant Human Verification in Registration
The Slider for Registration extension (mundophpbb/sliderverify) is a super lightweight and beautiful human verifier for the phpBB 3.3+ registration form.

What does it do?

1- Adds a "drag to verify" style slider to the registration UCP.
2- Only releases the "Submit" button after the user slides to the end.
3- Blocks automated bots without complicating the lives of real users.
4- Fully accessible: works with mouse, touch, and keyboard (arrows + Enter/Space).
