Recent research from Google reveals that users can enhance their online security by adding a recovery phone number to their respective accounts. Google worked in tandem with New York University and The University of California, San Diego on a yearlong study where they researched ways to combat targeted attacks and other security challenges. The team concluded the study by stating that during their research, simply adding a recovery phone number to the Google account can block up to 100% automated bots, 96% of phishing attacks and 66% of targeted attacks.
