    Hey folks, I would like to show you a new WordPress plugin and ask you for your opinion. The plugin allows you to find large files in your WordPress installation. This is useful, for example, when hard disk space is running low or backups are becoming too large or taking too long. If you like it, I am happy to get a rating on wordpress.org. I am thankful for any review / comment! Thanks, Marcel

    Replace CAPTCHAs with WebAuthn passkeys for bot prevention▲71

    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
