Google Meet is rolling out post-quantum cryptography for calls on laptop web clients and meeting room hardware. Google says users will see no interface change and do not need to turn anything on.
Google's October 12 release notice says the gradual rollout can take up to 15 days. It includes personal Google accounts and Workspace customers. Mobile support is described as coming later.
What changes on each device
| Where you join | What the notice establishes |
|---|---|
| Laptop browser | Included in the initial rollout |
| Meeting room hardware | Included in the initial rollout |
| Mobile app | Support is forthcoming |
| Admin console | No new administrator control is required |
Post-quantum protection addresses a long-term problem: someone could retain encrypted traffic now and try to decrypt it with a sufficiently capable future quantum computer. Google's notice says no such cryptographically relevant computer exists today. The change prepares current traffic for that possible future threat.
Participant access, recording permissions and the sharing of meeting notes remain separate controls.
Google's meeting-encryption explanation separates default cloud encryption from client-side encryption, which has additional account and setup requirements. The automatic post-quantum rollout applies to supported calls within that existing product structure.
Organizations with specific encryption requirements still need to confirm which clients and configurations meet them.
