Duo and Meet have combined into a new Meet app. Meet (original) users can download the new app.

Learn about call & meeting encryption in Google Meet

Google Duo has been upgraded to include both video calling and meeting capabilities. When communicating in Google Meet, 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. Your call will have a lock icon and an in-call watermark confirming it is end-to-end-encrypted.
  • Meetings: The ability to create or join a cloud-encrypted Google Meet meeting with a link when you’re ready. 

Learn more about the upgrade

To make sure your data is safe, Google Meet uses several encryption methods. For 1:1 and group calling where you directly ring a person, end-to-end encryption is used to mask data with a code that only you and the other callers have access to. For meetings in Google Meet, your information is encrypted in transit and at rest in Google's data centers. Organizations can also use client-side encryption to have full control of their encryption keys to add an additional layer of protection. Learn more about client-side encryption.

Learn how end-to-end encrypted calls work

End-to-end encryption:

  • Is a standard security method that protects communications data. 
  • Is built into every 1:1 and group 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.

For 1:1 and group calls, end-to-end encryption means that a call’s data (its audio and video) is encrypted from your device to your contact’s device. The encrypted audio and video can only be decoded with a shared secret key.

The key:

  • 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:
    • Google 
    • Other users
    • Other devices

Even if someone gains access to the call data, they can’t understand it without the key.

Learn more in Duo's end-to-end encryption technical paper.

To help fix problems, Google Meet, previously known as 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, Google Meet supports these cloud-encryption measures for meetings:

  • By default, meeting data is encrypted in transit between the client and Google data centers for meetings taking place in 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)
