How secure is the password manager?
Opera Mini’s password-manager security is dependent your phone’s physical security, password and locking protection. Like any other personal information stored on your phone, there is potential for information to be compromised without adequate security set on your phone. You can reduce any potential security risks of using the password manager by increasing the security level of your phone. For more information on how to do this, consult the phone manufacturer’s documentation. The password manager is available in Opera Mini 5.
