This is a great app for your gmail security. Login to Gmail and then add one more level of security with a 6 digit -- time& location based -- code from your smartphone. I also use it for Dropbox  but unlike the IOS version  for some reason the Android version doesn't title the Dropbox code with """"""""""""""""Dropbox"""""""""""""""" Please fix this issue Google  especially if I use it for other logins.""
