Google Meet now uses post-quantum cryptography

Calls in Google Meet will use post-quantum cryptography (PQC) for extra protection, starting now with laptop web clients and meeting room hardware, with mobile support coming soon. There are no visible changes, and you can continue using Meet normally. The updated encryption protects your data against potential future quantum computer threats.

The expansion of PQC to all Meet calls will help to secure infrastructure and services against the potential threat of a future cryptographically relevant quantum computer. No such computer exists today; however this change helps protect today’s Meet traffic from the theoretical risk of being harvested and decrypted by a future quantum computer, an approach commonly referred to as Store Now, Decrypt Later.

Google Meet has used quantum-safe encryption previously for client-side encrypted calls (CSE).

Google automatically implements all necessary updates to benefit all Meet hosts and participants. Administrators and end users don’t need to take any action.
