LifeLock is arguably one of the easiest identity theft software options to use. It’s this simple: 1. Sign up online. 2. Download software and install. 3. LifeLock scans your devices and accounts. 4. LifeLock sends you alerts via SMS, email, or phone. That's all you have to do. If you have ever downloaded an app to your phone or online, then this will be a cinch. LifeLock has PC, Mac, iOS, and Android compatible apps.
