Cannot sign-in Google account on Samsung Galaxy S with 2-step authentication I recently use 2-step verification to sign-in my Google account. 

But after turning this on, I cannot sign-in my phone since no SMS is sent to my phone.

What can I do to sign in now?
If you signed up for 2-step verification, you may need to enter an application-specific password in place of your regular account password. You can generate an application-specific password when you are authorizing access to your Google Account. This process takes a few minutes, and you only need to do it once per application or device.

Note: For Android devices running 4.0 or higher, you do not need an application-specific password and only need to submit your username and password. You'll be directed to another page where you can enter a one-time six-digit code.
