We want everyone’s experience with Hearthstone to be fun and as free of issues as possible. With that in mind, we’d like to share a quick reminder regarding your Hearthstone account security.
To have the best experience with Hearthstone, we recommend that you avoid rooting or jailbreaking the device you use to play. Doing so can cause adverse effects:
• It can increase your exposure to malware
• Unpredictable results can occur when running Hearthstone on such a device
• You might experience bugs or instability that you otherwise wouldn’t
In addition, it’s important that you never share your account information with others. A Blizzard employee will never ask for your password, and sharing it puts your account security at risk.
