Battle.net Mobile Authenticator for Windows® Phone 7 Devices

The Battle.net Mobile Authenticator, an application for mobile phones that provides an extra layer of account security, is now available as a free download for Windows® Phone 7 devices on the Windows Phone Marketplace. The Battle.net Mobile Authenticator provides a one-time password that you use in addition to your regular account name and password when you log in to a Battle.net account to play World of Warcraft or StarCraft II.
Versions for other mobile devices are also available for download here, or you can purchase a physical Battle.net Authenticator from the online Blizzard Store. Visit the Battle.net Mobile Authenticator FAQ for more information, or head to the setup page to get started after you've downloaded the application.

Check your phone's OS and then check whether there is a download for it.
HTC uses Android so yes you can get it on your HTC phone.

HTC also has Windows MOBILE phones. It's not all Android based.

Having been recently hacked, I was able to cut off the hacker thanks to the help from Blizzard and the Android Authenticator, so I can assure the WP7 users that this is one of those "must haves" (unless you already had a physical one ofc)
