Click the Edit icon for the Google Authenticator.
For the "Regenerate Key" option, click Regenerate.
Enter your master password, then click Continue.
Scan the QR Code via the Google Authenticator app on your mobile phone, replace your old account, then select OK.
Enter the verification code displayed in the Google Authenticator app, then select OK.
When prompted, click OK.
