Google Messages adds QR-code verification for RCS end-to-end encryption (beta)
Google has begun rolling out a QR-code-based verification method for end-to-end encrypted RCS chats in Google Messages. The feature is currently in beta and aims to simplify verifying that the person you’re messaging is the intended contact.
What’s changing
- Instead of comparing an 80-digit encryption key, you can now show a QR code or scan your contact’s QR code from the conversation details to verify keys.
- The 80-digit numeric comparison remains available as a fallback if the QR method fails.
- Google says this is part of a unified public-key verification system that will work across apps.
Requirements & rollout
- The feature is rolling out in Google Messages beta and targets Android 9 and newer.
- Not yet on the stable channel for all users — availability depends on beta enrollment and phased rollout.

Google is also moving away from SMS-based two-factor codes for Gmail toward QR-code scanning for sign-ins, aiming to reduce phishing and SIM-swap risks.
How to verify (quick steps)
- Open a conversation in Google Messages and tap the contact name or details.
- Choose the encryption or verification option.
- Select “Show QR code” on your device or “Scan QR code” to scan the other person’s code.
- If needed, use the numeric 80-digit comparison as a fallback.
