Can any site be hacked? in cryptocurrency it is assumed that any site can be hacked as long as the correct vulnerabilities are exploited. I am no trying to hack someone, I am trying to understand this from an educational perspective. how can a website that uses php login and 2 factor authentication be bypassed without tipping the server administrator or changing any passwords or other minute details. leave an email if you wish as I have more questions to ask if you don't mind
