Google Testing QR Code-Based Encryption Key Verification in Messages Beta

 

Google is reportedly rolling out a new security feature in Google Messages, aimed at giving users stronger protection for their RCS chats. According to a report by 9to5Google, the latest beta version of the app introduces a QR code-based key verification system, designed to enhance message encryption.

The feature is powered by the Android System Key Verifier and can be accessed in the Messages beta under a new "Security & Privacy" sub-menu. When users tap “verify encryption” in an RCS conversation, a pop-up appears with the option to "verify keys for this contact."

A large “Your QR Code” button is displayed in the center, showing the contact details associated with the code. To verify encryption, both users must scan each other’s QR codes, or alternatively, compare numerical verification codes—similar to the existing option in the Messages app. Testing also revealed that the Android System Key Verifier launches the scanner with a colorful viewfinder.

Google has been developing this upgrade since November, with the Android System Key Verifier app serving as the backbone of the process. As explained by Google, these encryption keys “help ensure only you and your contact can read the RCS messages you send each other.”

The keys are exchanged securely through QR codes, ensuring that only the intended parties can access conversations. If one user switches to a new phone, the keys may no longer match, requiring the verification process to be repeated.

Reports suggest the feature will only be available on devices running Android 10 or later. Since it’s still in beta, a wider rollout may take a few months. With Android 16’s QPR2 Beta 1 recently released, the new verification tool could be officially introduced toward the end of the year, possibly in December.
