Set or change a sync passphrase

When you sign in to Chrome and enable sync, Chrome uses your Google Account to encrypt your synced passwords. You can choose to encrypt all of your synced data with a separate sync passphrase instead. If you set a passphrase, you can use Google's cloud to store and sync your data without letting Google read it.

Learn more about sync passphrases

Before you decide to use a separate Chrome sync passphrase, here are some important things to know.

Where you’ll need to use it

Once you set a sync passphrase, you'll need to enter it in to Chrome on any device you're already signed in to in order to continue syncing. You'll also need it each time you sign in to Chrome on a new device.

Some Google features will not be available after you set a sync passphrase
  • Google Now won’t show suggestions based on sites you browse in Chrome.
  • You won't be able to view your saved passwords on https://passwords.google.com or use Smart Lock for Passwords on Android.
Where the passphrase is stored

Your Chrome sync passphrase is stored on your computer and will never be sent to Google. Only someone with your passphrase can sync your encrypted data to a new device.

What happens if you forget it

If you forget your Chrome sync passphrase, Google can't help you recover it. You'll need to follow the instructions below to reset Sync.

Note: Whether or not you use a passphrase, your synced data is protected by encryption in transit.

  • You forget your passphrase.
  • You want to change your passphrase.
  • You want to stop using a passphrase altogether.
What happens when you reset or delete your sync passphrase

Resetting or deleting your sync passphrase will delete all synced data from Google’s servers and disconnect all synced computers and devices, but won’t delete the data that’s on your computers or devices.

Don't worry: your current preferences, bookmarks, and passwords will remain available in Chrome. You'll be able to start syncing again by signing back in to Chrome on your devices.

How to reset or delete your passphrase
  1. Go to the Google Dashboard.
  2. Click Reset sync.
  3. Click OK to confirm.
  4. In the upper right corner of the browser window, click the Chrome menu Chrome menu.
  5. Choose Settings.

  7. If you’re signed in to Chrome with an account issued by your school or work, you may already be signed in. In this case, click Set up sync > Done.
  8. Repeat steps 4-6 above on all other devices where you use Chrome.

Note: This will delete all synced data from Google’s servers and disconnect all synced computers and devices, but won't delete the data that’s on your computers or devices. Don't worry: you'll still be able to see your current preferences, bookmarks, and passwords in Chrome. You can start syncing again by signing back in to Chrome on your devices.
