Dear Friend mfelber,I have tried this "DisplayUnlockCaptcha" several repeated times. There was no expected result or changes.I forgot to mention this in Original Post. Sorry. I was thinking what I have forgot? This was one major point.Surely, as you said it might help someone. But, as per my understanding, this is required for the people who have enabled "Double Authentication" (Two Step Authentication) in Google Security. Otherwise may be it is not required. There was one more; "Google App Specific Password" earlier. Now a days, it seems like Google removed that option, after introducing Second level Authentication Via SMS/Call or through Google Android "Authentication APP",.... It seems.I'm not getting done after passing all these, friend.I need solution. Someone who knows it better can definitely help me.-Regards,Sathya Charana SM
