Was your account recently locked due to a change in its access pattern?
If you recently changed your connection pattern, you can unlock your account with a simple password reset. Visit the Password Reset page to begin the process. The form can also be reached by clicking Can’t log in on any Battle.net login page.
If you did not recently change your connection pattern, someone else may have attempted to access your account using your password. We encourage you to follow our security checklist to secure your computer, and then perform a Password Reset to regain access.
Once your access is restored, consider adding Battle.net SMS Protect, a free service that allows you to quickly recover your Battle.net account using a mobile device. For more information, see the SMS Protect FAQ.
