As the name says, this software is there to stop oneself from accessing internet, thus I didn’t expect password protected security feature.

Website Blocker (Beta)

Website Blocker (Beta) is a free Google Chrome extension to block internet on Chrome. Here you can enter URLs to block, and also define time intervals separately for different websites to block them. Another feature of this Chrome extension to block websites is that, you can ask it to generate one time password to access a blocked website for 5 minutes.
