To help users protect their Battle.net accounts, Blizzard implemented a two-factor authentication option for the service.
Launched in 2008, this was initially through a separate device that could be purchased from Blizzard, encoded with the user's credentials.
The device fit on a keychain and would generate pseudorandom numbers linked to the player's account, which they would enter when logging into Battle.net to affirm their identity.
Later, Blizzard introduced the Battle.net mobile application for iOS and Android platforms in 2009, replicating the same functionality.
An update during June 2016 simplified the process, allowing the user, when logging into their Battle.net account from a computer, to simply press a single button on their connected mobile device to affirm their authenticity.
Though not required to use Battle.net, some game aspects require the user to enable two-factor authentication through either the device or mobile app.
