qr-code

The phishing and scam list the Verdetto app checks on the phone, compiled in the open from public feeds and signed, and the code of the services behind the app (the list build, the lookup copies, the metrics, the record) as Cloudflare Workers.

Sign-in and approvals through messaging apps for your website or app. No passwords, no forms, no SMS codes - zero typing, even on screens without a keyboard.

The user scans a QR code shown on a computer, TV or any other screen - or taps a button on their phone - and confirms with a single tap in a messaging app they already trust: Telegram, WhatsApp or another supported channel. Veriqa plugs into your application as a standard OIDC provider, with no frontend SDK. Open source under MPL-2.0.

The Verdetto website: a static build with no trackers, the in-browser link check, the help and legal pages.

The QR benchmark set: QR codes under damage, hand-shake and rotation, each with its expected text; a viewer that runs any scanner through it on a monitor and a scorer. Verdetto's own, CC0.
