Secure Your Gear with the Battle.net Authenticator

Get an extra layer of security for your legendary Diablo III loot with the Battle.net Authenticator!

Designed to buff your resistances against compromise attacks such as keyloggers and Trojans, the Battle.net Authenticator works by providing you with a secure, one-time use passcode that’s unique to your Battle.net account. Once attached to your Battle.net account, you’ll periodically be prompted to enter one of these codes in addition to your regular account password when logging into the game client or Battle.net Account Management.*

Pretty simple!

Find out which type of Battle.net Authenticator is best for you:

  • Battle.net Authenticator Mobile App - Perfect for players with access to a smart phone or compatible mobile device, and available for free for iPhone, iPod Touch, and Android users.

For additional security tips, be sure to read our full article on account security and visit our dedicated website at http://us.battle.net/security/.


*Note that by default, after you've successfully logged in with an Authenticator a certain number of times from a certain location, you won't be prompted for a code every time you log in. You can require Battle.net to ask for a code every time by modifying your Security Options in Account Management, located here.
