Can I turn the extra security of the Battle.net Authenticator on and off as I wish?
 
Yes, you can do so through your Account Management Login page using the serial number on the back of the Battle.net Authenticator.

 Does the Battle.net Authenticator replace my password and secret question?
 
No, the Battle.net Authenticator is only there as an optional measure to augment account security. It does not replace standard security measures. You will still be asked to enter the account name and password when logging into the game or Account Management, and should not share that or your secret question information with others.

 Will a Blizzard representative ever ask for my Battle.net Authenticator information?
 
Yes. Blizzard may ask for the serial number on your Battle.net Authenticator, typically to help you associate it to an account or to verify your ownership of that authenticator.

 What if my Battle.net Authenticator stops working or has a technical problem?
 
Blizzard will have several support options available to assist you and ensure that the impact on your play experience is minimized in the event of a problem with your authenticator. You may contact us through our Support Site, or contact us via phone.
