Sensitive information including logins to social media accounts was among the data exposed in what some believe is the largest breach in U.S. history.

One of the key risks of a data breach this big is how easily cybercriminals will be able to access multiple accounts, especially for those who reuse passwords. A survey from NordPass indicates that as many as 62% of Americans, 60% of Brits and 50% of Germans admit to reusing passwords across multiple online accounts.

A record-breaking data leak exposed 16 billion passwords on online services such as Apple, Google, and Facebook.
