How to implement cross-device authentication (QR code login) with Supabase?
edge functionsrealtimeauthHi everyone 
I’m working on an authentication flow similar to WhatsApp / Telegram Web, where:
A user is already logged in on mobile
They open the app on another device (browser)
The browser shows a QR code
The user scans the QR code from mobile
The browser session gets authenticated automatically
I’m using Supabase Auth and wanted to understand:
What’s the recommended way to securely link the QR scan to a pending browser session?
I am unable to get any info from docs to get this work securely.
