Please be informed that if you forget the password then SanDisk does not have any method to bypass the password security feature on Secure Access software. SanDisk has not built in any back door or password reset methods. If the password feature is enabled and you forget the password there is no back door entry to unlock the drive. You can format the drive, which will perform a secure erase (drive wipe) and data recovery will NOT be possible. Moreover, if you want to use Secure Access again then you need to first format your flash drive after taking back up of all your data which is in your flash drive.
