For BlackBerry devices

On your phone, open the Google Authenticator application.
If this is the first time you have used Authenticator, click the Add an account button. If you are adding a new account, choose “Add an account” from the app’s menu.
To link your phone to your account:
- Using QR code: Select Scan account barcode. If the Authenticator app cannot locate a barcode scanner app on your phone, you might be prompted to download and install one. If you want to install a barcode scanner app so you can complete the setup process, press Install then go through the installation process. Once the app is installed, reopen Google Authenticator, point your camera at the QR code on your computer screen.
- Using secret key: Select Manually add account, then enter the email address of your Account name in the box next to Enter account name. Next, enter the secret key on your computer screen into the box under Enter key. Make sure you've chosen to make the key Time based and press "Save."
