Overview
- The QR-based key check is appearing in the latest Google Messages beta and has not reached the stable release.
- Users access a new Security & privacy sheet from Verify encryption, then mutually scan each other’s codes to confirm identities.
- An 80-digit code comparison remains available as a fallback for cases where QR scanning is not feasible.
- The Android System Key Verifier handles the scanning experience, with support targeted for devices running Android 9 or newer.
- Google positions this as part of a unified public-key verification system expected to extend to third-party apps, with Contacts status views noted but not fully live.
