The Blizzard Authenticator lets you protect your account and games.


The app offers two-factor authentication, protecting everything from your most storied World of Warcraft characters to your meticulously crafted Hearthstone decks. The authenticator app provides a one-touch button experience so you can approve or decline any login attempt. With the Mobile Authenticator, you can rest easy knowing that your account is more secure.

Note: This app is not compatible with classic games (like Diablo II and Warcraft III) except for StarCraft: Remastered.
