If you have changed your Google Account password, follow the steps below:

  1. Click the error message and enter your Google Account username and the new password.
  2. If prompted for a passphrase, enter your sync passphrase. In some cases it may be the same as your Google Account password.

  2. If you're prompted to sign in, enter your Google Account username and password. Do not enter an application-specific password here.
  3. You will be asked to enter a verification code. Generate the password on your Authorizing applications and sites page and paste it into the dialog.

    Application-specific passwords are not the same as verification codes.

Sync Error: Update sync passphrase

You will see this message when you set a sync passphrase on one computer or have recently changed your Google Account password.

If you’ve set a sync passphrase on one computer, you’ll need to enter the same passphrase on all of your other syncing computers. On other syncing computers, you may see an error on the Chrome menu Sync error prompting you to update your passphrase.

Follow these steps to fix this issue:

  1. Click Sync Error: Update Sync Passphrase in the Chrome menu.
  2. In the "Advanced sync settings" dialog, under the "Encryption options" section, you will see one of the following:
    • “Your data was encrypted with your Google password.” If you see this message, enter your previous Google Account credentials.
    • “Your data was encrypted with a sync passphrase”. If you see this message, enter the sync passphrase that you created.

What if I’ve forgotten my custom passphrase?

If you no longer have access to your custom passphrase, you’ll need to reset sync.

  1. If your synced data (bookmarks, apps, etc) is available on your local computer, sign in to your Google Dashboard.
  2. In the Chrome Sync section, click Stop and Clear. This step will remove the data from Google’s servers. The data on your local computer won’t be affected.
  3. Wait a few minutes before signing in to Chrome and re-enabling sync on your computer.

You see the following error messages in the "Sign in" section of the Settings page.

This account is already being used on this computer

You will see this message if you are already signed in to Chrome with the same Google Account on a different Chrome user. Click on the Chrome user icon on the top corner, and in the drop down select the user associated with the Google Account you are trying to sign in to Chrome with.

Someone previously signed in to Chrome

Someone with a different Google Account was previously signed into Chrome. By signing in to Chrome, you may be associating someone else's Chrome settings and preferences with your account.

If Chrome has stored information like bookmarks or history that you don't want to sync with your account, such as on a shared computer, click "Create a new user".

If Chrome was previously signed into with an account that you own, and you want to sync your Chrome information with a new account, click "Sign in anyway".
