By some estimates as many as 1 in 4 people claim to have had one of their online accounts hacked.A mobile app (currently Android, with iOS to follow soon) that promises to monitor an array of online accounts for suspicious login or attempted login activity.
It does this, in part, by building a profile of your usual log in parameters, such as sign-in locations, times, and device types, and then alerts you of any suspicious activity. It is called Logdog. Technically the way the app works is that you give it permission to log in on your behalf to the accounts that you wish to monitor — Facebook, Dropbox, Gmail, Evernote, Yahoo!, and Twitter are supported — and from there it continually monitors those accounts via their own respective activity logs for anything suspicious. -
