I found this cool app called Cold Turkey. It allows you to block any website you want and let's you lock the block with various methods. My favorite method is random text - it locks the block until you have typed out a certain amount of characters, up to 5000. This is the best way to protect your locks in my opinion because other methods are too easy or too difficult to bypass. Cold Turkey is desktop only but there is an app for mobile called Focus Me. Hope this help you guys.
