Product details
The Battle.net Authenticator is linked to your World of Warcraft account or your Battle.net account. It was designed as an additional authentication method for your account, providing you with the security of two-factor authentication. Each time you log in using the Battle.net Authenticator, you will need to use a unique, one-time password in addition to your regular password.
Log in with these two methods completely at ease: your account is less vulnerable to keyloggers, trojans, or other malicious attacks.
Simple and easy to use: press a button to receive your additional password. Take your Authenticator with you wherever you go and rest assured that your account information is secure. It is robust and durable, can be used for years, and is easy to replace.
