Replace CAPTCHAs with WebAuthn passkeys for bot prevention
I built Nocaptcha after getting frustrated with traditional CAPTCHAs both as a user and developer. WebAuthn passkeys offered a promising alternative that's both more secure and user-friendly. What makes Nocaptcha different: - Uses WebAuthn standard instead of puzzle-solving - No need for users to remember passwords or solve puzzles - Open source Current limitation: Working with W3C WebAuthn Community Group on true passkey disposal for this use case. Looking for feedback particularly on: 1. Integration experience 2. User experience compared to traditional CAPTCHAs
In plain words
Nocaptcha is an open-source bot prevention tool that replaces traditional CAPTCHAs with WebAuthn passkeys. Instead of solving puzzles, users authenticate using the WebAuthn standard, eliminating the need to remember passwords. Developers can integrate it as an alternative to conventional CAPTCHA systems. The project is still refining passkey disposal mechanisms and welcomes feedback on integration and user experience compared to existing solutions.
