About BlackBerry Wallet security
BlackBerry® Wallet is designed to keep your stored information safe.
When you open BlackBerry Wallet for the first time, you create a master password. You must type this password each time that you want to access your information, such as when you make an online purchase. To protect your information, BlackBerry Wallet also prompts you for your password when you return to BlackBerry Wallet after using another BlackBerry device application.
If you type the password incorrectly ten times, BlackBerry Wallet deletes all of the information that you have added.
