Using 2-step verification with Google Authenticator on an Android handset provides good security for accessing Gmail and other Google services. What I am curious about is whether Google Authenticator can provide support for all Gmail accounts on the phone (multiple Gmail accounts can be added to a single handset under the Accounts menu in Settings). Will both accounts authenticate using the same codes?

I know that the Authenticator app does allow for manually entering accounts. I haven't yet set up a second account with 2-step authentication, though. – Al E. Jul 6 '11 at 12:41
Both accounts would definitely require separate codes. I don't know if Authenticator can take more than one account, but if not you could try setting it up with one account, backing up the app's data with Titanium, clearing the data, setting up the second account, make a second backup, and then each time you need a code just restore the backup you need. Depends how the app stores the account data. – Matthew Read Jul 6 '11 at 15:09
It supports third-party account too. For example, I use it for LastPass 2-step authentication.. – SS-3 Apr 1 '12 at 22:48

Yes, the Android as well as Blackberry versions of Google's Authenticator app supports multiple accounts.

Press MENU and choose SCAN BARCODE after you've set up your new Google Account for 2-factor auth to grab the displayed barcode or enter details manually.

Google Authenticator creates two-step verification codes on your phone.

Google Authenticator works with 2-step verification for your Google Account to provide an additional layer of security.


  • Automatic setup via QR code
  • Support for multiple accounts
  • Time and counter based code generation

To use this app, you need to enable 2-step verification on your Google Account.
