It’s just note for all, who use Google 2-step verification and want to share photos and video from Samsung Smart Camera via Wi-Fi (directly to Picasa and Youtube).
Signing in to mobile devices with application-specific passwords
Once your users enroll in 2-step verification, they may need to use application-specific passwords in addition to their verification codes. For installed applications that don’t have a 2-step verification field, your users will need to enter an application-specific password once per device or application in place of their regular password to access their Google Account.
Common devices and applications that require application-specific passwords are: Gmail and Google Calendar on Android-based phones, ActiveSync for Windows Mobile and iPhone, and IMAP clients such as Thunderbird. See Sign in to mobile or desktop apps for more details.
