If you use Passbook frequently on your iPhone, you may have noticed that certain passes use your location in order to give you easy access on your lock screen to a specific pass when you're within the vicinity. Some of those passes may contain personal information or allow for someone to charge an item to a gift card or account.
If you'd like to prevent unauthorized access to your passes, you can easily do so within Passbook. Follow along and we'll show you how.
That particular pass will no longer show up on your lock screen when you're within the vicinity. Alternately, you can always disable access to Passbook from the lock screen to take care of any concerns you may have with unauthorized use.
