In January 2019, security researcher Troy Hunt uncovered the biggest leak of email addresses and passwords in history. Dubbed Collection #1, the breach comprises several individual data leaks from different sources, for example social media sites or email addresses.

Generally, attacks are from a single source, such as the 2018 Facebook breach which led to the leak of 14 million users’ names and contact details. For Collection #1, however, 87GB of data from different sources, including more than 770 million email addresses, has been compromised.

Hunt, who runs an online service which allows users to check if their email address has been leaked, advises using password management software. MyCena’s mix-and-match security system, for example, stores passwords locally and combines multiple identifiers such as fingerprint and voice passphrase.
