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.
