Blizzard has come up with a new feature in the form of one-time password authentication, which is generated by this keychain. First, you synchronize your account with the keychain by entering its unique number. From that moment on, Battle.net knows that you, as its owner, and no one else, has the authority to handle your identity in the Blizzard game world. The generated access code is valid for only one minute, so hackers are completely helpless without your keychain!

Main features:
Superior battle.net account security at the same level as banks use for client accounts. Easy to use - press a button to generate a code.
You can always keep a small keychain with you.
Quality workmanship

After connecting the keychain to your Blizz account, you will receive a new unique pet in the mail in World of Warcraft.
