Bye, Google Authenticator tokens

Update 2013-09-07: Google released a new version which restores the lost account tokens. If you’ve already re–added your account tokens, please see this caveat.

Before you update to Google Authenticator 2.0.0 for iOS, disable two–step (or wait until 2.0.1). It removed my tokens from the app, and I had to re–add them again. Boo.

To fix this with a Google account, you’ll need to do the following:

1. Go to Account → Security → Edit (under 2–step verification).
2. Under How to receive codes and across from Mobile application, click “Move to a different phone”.

As for the backup codes you printed, if you click the help icon (question mark) next to “Remove Switch to phone”, it says:

When you want to switch to a different phone, select “Move to a different phone” and follow the instructions to configure the Authenticator app on your new phone. This will not invalidate any of your existing application-specific passwords or backup codes.

Or, you can add your Google Authenticator Tokens into Authy. Thanks for the tip, James!

Dropbox: In Account → Security, click the Edit link next to Authenticator app.
