Google Duo has been upgraded to include both video calling and meeting capabilities. When communicating in Duo, you can use either:
- 1:1 and group video calling: The classic Duo end-to-end encrypted experience that involves ringing a number or group directly.
- Meetings: The ability to create or join a cloud-encrypted Google Meet meeting with a link when you’re ready. Meet meetings happen in the Duo app.
Learn how end-to-end encrypted calls work
- Is a standard security method that protects communications data.
- Is built into every Duo call. It’s on by default and can’t be turned off.
- Only lets people in a call know what’s said or shown.
- Doesn’t allow Google to view, hear, or save the audio and video from your call.
End-to-end encryption masks the call data with a code that requires a key to decode.
- Is a number created on your device and the device you call. It exists only on those devices.
- Disappears when the call ends.
- Isn’t shared with:
- Other users
- Other devices
Even if someone gains access to the call data, they can’t understand it without the key.
To help fix problems, Duo uses some info about your calls, like:
- Why and when a call is dropped or delayed
- The device IDs of the caller and receiver
- Phone numbers of people in a group call
This info is securely stored for about a month on Google servers.
Learn how cloud-encrypted meetings work
To help ensure data security and privacy, the Duo app supports these cloud-encryption measures for meetings:
- By default, meeting data in the Duo app is encrypted in transit between the client and Google data centers for video meetings taking place in any Google Duo or Google Meet.
- By default, meeting recordings stored in Google Drive are encrypted at rest.
- Meeting encryption adheres to:
- Internet Engineering Task Force security standards for Datagram Transport Layer Security (DTLS)
- Secure Real-time Transport Protocol (SRTP)
